Transcript: This is a talk I originally prepared to present as part of the 2206-2007 convocation series at Illinois College. Since then I have given it before several other audiences, and with every presentation I’ve had more people ask, will this be online. Finally, I can saw yes. Here’s the link. Please enjoy.

In today’s crazy world, it is easy to get lost in the details of our overly busy lives. There are projects, deadlines, business meetings and family meetings all demanding our attention. I suspect at least some of your employers have led you to believe their project should be the most important thing in your life right now. And I suspect that at least one person in your family has led you to believe that being at their home on time for some particular family gathering is the most important thing you can do this month. With all these specific day-to-day details demanding attention, it is hard to find a moment to step back and consider the big picture.

Especially when the big picture encompasses the entire universe; past and present, and possibly even parallel.

Right now, I invite you to set aside the details of today, and consider instead the details of the first day, and the implications those details have in creating the universe we live in.

Science in the 20th century has made huge strides in understanding the science of our universe.

We went from not understanding how physical traits like eye color are passed from parent to child, to James Watson and Francis Cricks 1953 discovery of DNA to the 2000 completion of the first draft of the Human Genome project, which is mapping the entire genetic structure of the 25,000 some odd genes that make up each of us.

We went from seeing the entire universe as a continuous distribution of stars and nebulae; to Edwin Hubble’s 1929 discovery that the Andromeda Nebula is actually a separate galaxy apart from our own; to the 1989 realization by Margaret Geller and John Huchra that we live in a universe of structure, with galaxies tracing out voids and filaments and clustering in some cases by the 1000s in giant super clusters.

We went from viewing the universe as a stationary place – where everything was as it always had been and always would be – a Universe that Einstein held in place in 1915 when he published his General Theory of Relativity with a cosmological constant – to seeing Hubble’s late 1929 realization that the universe is expanding, to the 1998 discovery that the universe is not just expanding but accelerating apart.

From the DNA of life to the cosmological expansion of the universe, we have found rules to describe our place in the cosmos. But the rules that describe our place, can’t answer the more fundamental questions of why does our universe exist and why is our universe the way that it is.

Today, 21st century science struggles with these more fundamental questions. Physics as we know it does not dictate our universe should be just as it is. Rather, many other possibilities are possible and perhaps even more probable. But we are here, and this has consequences on how we must view our universe, and on what forces might make the improbable possible. It is the improbability of our place in space, and the consequences of our reality that I want to discuss today.

Since this is a discussion of science, we need rules to govern our thinking and our logic. Without rules, it is possible for anyone to say anything and say it is true, just because that anything fits into their own personal set of beliefs. Science, starts with the premise that it is possible to run experiments and make observations that tell us about the universe around us. Any theory I develop to explain the universe must conform to past experimental results and observations, and a good theory can be used to predict the outcome of future experiments and observations.

Put simply, as a scientist, when I observe that a tossed ball goes up and comes back down, I believe that I am observing a real phenomenon. Now, it is possible for me to theorize that any object thrown up into the air will also go up and come back down, and to predict that if any of you toss a ball up into the air, you too will observe the ball go up and come back down.

So far so good, I have a theory, it fits past observations, and it makes concrete predictions. As a scientist however, I also have to be willing to say my theory is wrong if it can be disproved experimentally.

This means, if I observe an object get thrown into the air and not come back down — for instance a space probe getting thrown into space by a giant rocket, that rather than falling back to Earth goes off to explore Mars – then I have to modify my theory to incorporate the new observations. Now, my theory would have to say, any object thrown upward will come back down unless its velocity is greater than the escape velocity needed to get away from Earth’s gravity. Such an object will go up, and keep going until it encounters the gravity of something else. Ideas build and grow, and incorporate into themselves the results of each new experiments. I started with my observations of my ball, but then incorporated my observations of a Mars probe.

In the history of science, Newton’s theory of gravity grew into Einstein’s General Theory of Relativity, which someday will probably grow a new name as the theory it self grows to include results pertaining to quantum mechanics and the physics of black holes.

In science, we also have the basic rule that theories are as valid on the other side of the universe as they are here in this room. This means that any theory of tossing balls here on Earth will also be valid on the other side of the cosmos, where some green handed individual might perform the same experiments I perform. Science is one of the few languages that isn’t rooted in culture or even planet orgins. The physics here is, simply, the same as the physics everywhere.

Along with the rules being the same everywhere, science also assumes that if you look at a large enough chunk of space, the universe is the same everywhere. Our neighborhood of space, if we define it large enough, is the same as every other neighborhood, with the demographics and the same evolution. No neighborhood is special. Put scientifically, using really big words, this basic tenet, dubbed the Cosmological Principle, states that the universe is homogeneous and isotropic.

We also have one more rule that tries to govern us, and that’s the principle of mediocrity. This is the rule that we don’t live in a special place, a special time, or a special anything else. There should never be any result that rests on us being at just the right place and moment in space and time. In considering this rule you again have to think big. The time we live in on the planet Earth, is special. We live during the halceone extinction, and have the privilege of watching global warming. We also live during a special time when our sun isn’t too big or too cold or to hot, but is just right for life. When considering the principle of mediocrity you have to look at the entire age of the universe and expance of the cosmos and say, our Sun isn’t special, our galaxy isn’t special, our lifetime, against all the other 60 to 100 year blocks of time isn’t anything great. In the local scheme, we live in far too interesting a time, but cosmically our place is space isn’t anything extraordinary.

So there you have it: everything is the same everywhere and none is special. We simple live to observe the same stuff you can observe anywhere, and we use those perfectly boring observations to built theories that, if they are scientific, are able to predict what future observations will see.

With these basic ideas, I have the intellectual tools I need to explore the universe, and what a beautiful universe it is. Today’s modern story of Genesis, starts with a Big Bang that marked the beginning of time and space. From a nothing that some describe as a quantum foam fluctuation, there emerged energy that would condense into the universe we now occupy. For a brief moment, all the atoms that make up you and me and the entire universe were condensed into a single speck of pure energy.

As that early, energy filled universe expanded, it went through a period of exponential growth that is referred to as inflation. During this period, the space itself expanded so rapidly that two points would appear to separate faster than the speed of light. Now, don’t misunderstand this. The objects didn’t actually move faster than the speed of light, but the actual space grew, as though the entire universe was a piece of graph paper that kept getting run through a Xerox machine set on enlarge.

In this situation, the actual place on the universe that a given point or three might be located, would stay constant with time, but the universe itself expanded, making the space between those spaces bigger, making it appear that the points were moving apart. The apparent velocities, as the grid carried the points with it from a confined space to an enlarged space, could have seemed to be as high as several times the speed of light, but appearances aren’t always reflections of reality, and the points in space didn’t actually move on the grid of space time. The grid itself simply enlargeded.

Had the inflation gone on longer or pushed things farther apart than it did, the material in the universe would have been spread out too much and become too smooth for stars and galaxies to later condense. Had inflation not spread out matter as much as it did, it might have clumped up so much that everything collapsed back together, producing a big crunch shortly after the big bang. Physics, as we know it, doesn’t require inflation to work the way it did, but the universe we live in requires there to have been inflation in order for us to exist.

As the epoch of inflation ended, the universe cooled and matter began to condense. From Einstein’s famous E=mc^2 we know that mass is just another face to energy, and that the two can transform from one to the other. As our universe expanded, it cooled, and matter was able to solidify out of the energy.

The catch is that when energy changes into matter it should also produce anti-matter. For every proton – the key ingredient in atoms – there should also be an anti-proton. For every electron there should be a positron. The reason I say this is a catch is very simple – as you and I look around this room we don’t see anyone made of anti-matter. As astronomers look out across the sky, we do not find anti-matter stars or galaxies. In fact, while anti-particles are observed, they are transitory things, which quickly annihilate as they collide with regular matter. If, at the beginning of the universe, matter had condensed into equal parts matter and anti-matter, than no matter should exist today.

But, we do have matter. We exist. Observationally, we know that somehow, for every 10 billion anti-matter particles that formed, there must have been 10 billion and 1 particles of regular matter. When the 10 billion matter and anti-matter particles combined they left behind 1 particle of matter and a lot of light. This fine tuning created a universe that was just right for us to be able to be in this room, but that is mathematically ugly, requiring asymmetries in the matter and anti-matter. These are asymmetries that theorists can’t make fall naturally out of any equations. It seems the universe simple was made just so.

And it made it just so in the flash of an eye. Within a second, all this was over. Inflation was over. The self-annihilation of matter on anti-matter was over. And then, from about 100 seconds after the big bang until 3 minutes after the Big Bang, the entire universe did its best imitation of the inside of a star. Proton’s collided together with such high velocities that nuclear reactions built hydrogen into helium, and a little bit of lithium and beryllium. The results of this early, Big Bang Nucleosynthesis is still visible in the ingredient lists of the oldest stars. After the Big Bang the universe was 25 percent He, and little bit of deuterium, a heavy form of Hydrogen, and it contained trace amounts of Lithium.

After those first three minutes, it was too cool for nuclear reactions to continue, but too hot for much of anything else to occur. For nearly 400,000 years electrons, atomic nuclei, and radiation formed a thermally interacting soup that simple expanded and cooled, but didn’t do much else. Finally, around year 380,000 the universe cooled to a point where normal atoms could form, and the electrons bonded with the nuclei, and the radiation was free to fly away.

That radiation, the radiation created when the matter and the antimatter collided, was set free when electrons bonded with nuclei, and it continues to permeate all of space today and we observe it in the form of the cosmic microwave background. Slight temperature differences in the universe at the moment of recombination, reflect slight changes in density from one part to another. And when I say slight I mean slight – the variations seen in this temperature map represent differences of just one part in 100,000.

Today, the Cosmic Microwave Background has a temperature of 2.725 degrees above absolute zero with fluctuations of just 0.000018 degrees.

These small variations would eventually collapse into the large-scale structures – the galaxies, and galaxy clusters – of today’s universe, but that would take time. The largest structures formed first, creating the scaffolding into which all the matter would flow. Within these structures the first generation of stars formed as material streamed into forming galaxies. And at the junctions of these structures super clusters formed at the location of the largest temperature fluctuations. Today we can see the distribution of temperature fluctuations reflected in the distribution of matter in space.

Initially, the neutral universe was a dark place. It stayed dark for almost 400 million years while the material slowly collapsed. For almost 400 million years the universe consisted entirely of neutral gas that didn’t create light and in fact would have been opaque to any light that might have existed. Than finally, one day the first stars were born and their light cleared the opaque gas, making the universe transparent. At that moment the just forming galaxies lit up the early universe. In the billions of years since then, stars have continued to be born, and galaxies have continued to grow, and today we can trace out the evolution of these objects using telescopes as time machines.

Because light travels at a finite speed, it takes time for information to travel from one object to another. Over small distances, such as the distance from me to any of you, this time is unnoticable. I speak, and faster than I can blink, you see my lips move if we were in the same room. Still, in all truth, you can never see me in the moment, and I can never see you as you appear at the exact now that I say now. The light always must take some time to travel, even if it is sometimes an unimaginably short time.

As distances grow, however, the time it takes light to travel becomes meaningful. When reporters try and report live from overseas locations, we can see the lag introduced as a question travels from the american studios, up to a satellite, across to a different satellite and then back down to the reporter, only to have to return again. As we move farther and farther and farther away, this time grows. When we look at the Sun, we see it as it appeared 8 minutes ago. Jupiter is seen as it was 40 minutes ago. Scientists sending probes to distant planets must program the robotic explorers to act autonomously because it isn’t possible, with even a few minutes of lag, to drive a space ship like a remote control car.

And consider this fact: Light from our neighboring galaxy, Andromeda, takes more than 2.36 million years to reach us. This means that we see Andromeda as it was when early humans were just starting to walk the Earth.

As we look at the most distant objects, we are able to look back at our universe’s infancy. What we find is a fascinating story of gravity and some mysterious expansion causing force playing a game of tug-a-war with our expansion rate. In the early days of the universe, matter dominated everything, and the gravitational force of everything on everything else worked to slow the expansion left over from the original Big Bang. Until recently, it was believed that our universe might someday reverse directions, and collapse in on itself, or that perhaps it would slowly coast outward at ever slowing rates that might or might not eventually hit zero.

But, all because you think something is true doesn’t make it true. In 1998, the entire astronomical community had to rethink how we view the universe when it was discovered that the rate of the universe’s expansion began to accelerate 5-6 billion years ago.

Using type 1a supernova, a type of exploding stars that give off set amounts of light, astronomers can measure distances out to the far corners of the universe the same way that you estimate the distance to an oncoming car at night. The light from any standard light source appears more or less bright depending on the distance to the light. If you are standing in the middle of the road and see really bright headlights you might correctly realize you’re about to get hurt, while if you see really faint headlights, you might decide you can pause to pick up a penny in the road. Your brain is automatically doing math, and astronomers do that same math to figure out where supernovae of different brightnesses are located.

Once we know where and when a supernova is located, we can get at the expansion rate in their corners of time using the same technique that policemen use to measure the speed of your car. When a light is either moving or reflecting off a moving object, it gets shifted in color.

The color shift we observe is related to the direction of motion. As an object moves toward an observer, the light waves get squished together, appearing more blue. Conversely, light waves get spread apart, appearing more red, when an object moves away from an observer. Today, astronomers have distance and velocity information for dozens of supernovae spread all over the cosmos, and from this information we can plot the changing expansion rate of the universe.

From our plots, we know that roughly 5-6 billion years ago, the universe’s expansion began to accelerate. The culprit, the repulsive force, behind this acceleration is called Dark Energy. It’s always been there, affecting each cubic meter of space, and trying to push things apart, but it’s only in the modern universe, where the space between objects is vast, and the total volume of space is something much greater than vast, that Dark Energy has been able to become a major effect.

Each cubic meter of space has the same repulsive quality. As the universe continues to expand, each new square meter of space has the same repulsive quality, and the total amount of repulsion grows with the universe. As the universe expands, it will accelerate itself apart as an ever-growing proportion is made up of dark energy.

Think of it this way, when you first mix the ingredients for bread dough, the dough is dense, and every square centimeter is primarily made of flour. As the dough rises and is eventually baked into bread, each square centimeter consists more and more of air. Now imagine the dough could expand forever until each square centimeter consists of only 1 grain of flour, and all the rest of the space is air. In our own universe, the mass is getting spread out more and more each moment and dark energy fills in all the intervening spaces.

As best as anyone knows, dark energy arises from the vacuum of space. In this vast, seeming nothing, there is energy, and this energy constantly boils with particles that are forming and annihilating one another. Some of these particles, those that fall into the category of bosons, such as protons and neutrons, have a positive energy, and those that fall under the label fermions, like electrons, contribute a negative energy. Observationally, the total amount of dark energy seems to work out to an energy equivalent to roughly 3 protons per cubic meter.

This is a very small value – which is good, because if it were any larger the universe would have been shredded apart. Just an increase of a factor of 10 would have prevented our universe from forming stars, galaxies, planets, and life. This is called the big shred, and some strange coincidence of space and time saved us from that fate. The physics, as far as we know, doesn’t require dark energy to be so small, in fact, most theories predict that it should be 10 to the power of 120 times larger! Theory doesn’t even require dark energy to be positive. Because the universe happened to be set up with a positive dark energy of this roughly 3 protons per cubic meter and no larger we are able to exist.
And it is because of another magically just so number that we are able to understand dark energy and also be able to exist.

That other magic number is the the fine structure constant.

When we observe supernovae, we study the way they give off light in some colors and not in others. Every atom gives off it’s own specific set of colors. When you see a neon “Open” sign, you are seeing red light given off by excited neon gas. Blues come from argon, and purple from Xeon. These colors come from the energy transitions of electrons orbiting the proton neutron core within an atom.

Let’s consider for a moment the atom most required for human life – carbon. This atom consists of 6 protons, 6 neutrons, and 6 electrons. It is formed in stars like our own Sun, and can be found throughout the galaxy.

When we observe supernovae, we study the way they give off light in some colors and not in others. Every atom has its on characteristic energy levels that orbiting electrons are allowed to occupy. Light carries energy that corresponds to its color. When light of the wrong color collides with an atom, nothing happens, but when light of the right color comes in, for instance when light from the center of a supernova collides with matter surrounding the supernova, the light gets absorbed.

Atoms can also give off light. That red neon “Open” sign you see documents the energy drop of electrons within the gas.

Sometimes light is absorbed by atoms, and sometimes atoms give off light.

These absorptions and emissions lead to bright and dark bands in the spectra of the objects we observe, whether they be stars, nebulae, supernovae or galaxies. The exact fingerprint of these atoms is governed by quantum mechanics, and in the midst of a lot of elegant equations sits an experimentally determined fine structure constant.

The value of the fine structure constant isn’t defined by the physics. It just is. Along with determining fine divisions within the colors we see in neon signs, and in supernovae, the fine structure constant also defines how well the cathode tubes in old TV’s were able to form a picture, and it plays a role in the electromagnetic force between all charged particles. If its value changed, the properties of all atoms would change, and we probably would not exist to view supernovae and the expansion of the universe.

The list of things that appear to just be the way they are “just because” is an ever-growing list. One of the holy grails of science is that one underlying elegant equation that will explain everything; the fine structure constant, the amount of dark energy, the length of the inflation epoch, the proportion of matter to anti-matter… all these things and more we keep hoping will fall out of some magic perfect equation that elegantly sums up everything.

But we can’t find that theory.

Einstein spent his life searching for it. Hawking has looked. Every great cosmologist has asked, “Hmmm, what if…,” and they’ve come back with nothing certain. There is string theory – a mathematical model that attempts to unify all of the forces by assuming particles are multi-dimensional strings rather than point sources, but… There are perhaps 4 people in the world fully understand string theory, and there no one who has been able to come up with a way that we can either verify or falsify string theory. Without experimental testing, string theory can’t be considered science. It is just a pretty mathematical art form that might some day grow into making testable predictions. But, it’s just not there yet.

So for now, as I scientist, I find myself in a universe that has a lot of things that seem to be just so, just because. I also have this rule that states that I can not live in a special time, place, or special anything else. These two things seem to be contradiction. I could brush it off and say it’s a coincidence, don’t sweat it, but… But at a certain point, if the same person, or in this case the same universe, wins the lotto day after day after day, you have to wonder if something funny is going on.

And right now a lot of scientists are wondering how it is that so many things are so improbably just so.

It seems that there are three possibilities.

1) We could of course not really understand the universe. It could be there is some yet undiscovered underlying rule, some beautiful set of equations, that will dictate all the impossible coincidences must exist. This is the hole grail so many cosmologists seek.

2) Another possibility is there is force outside our universe, outside our space and time, that is dictating the constants of our cosmos. Perhaps there is a God, a watchmaker, a greater power tweaking our forces to make life possible. But, this possibility is beyond the testing of science. We don’t know how to verify or falsify it and, as scientists, we must set it aside as something beyond science.

3) The third possibility is to some the ugliest and to others the most elegant. This third theory says that our universe is just one of many and that our improbable reality is able to occur because every possible combination of constants exists somewhere in the multiverse of universes.

This third theory may or may not be testable. And this possibility, falls out of many different ideas.

There is the probability argument: In theory, if enough monkeys pound on typewriters for enough years, Hamlet will emerge, and it makes sense to say that if enough universes are allowed to exist, eventually life will emerge. But saying that something makes sense just isn’t enough.

Luckily, many scientists find more compelling ways to get at multiple universes.

According to Quantum Mechanics, the outcome of a quantum event doesn’t exist until it’s observed. This is the premise behind the Schodinger’s Cat thought experiment. The experiment goes something like this: You lock a cat in a sealed container. In the container with the cat is a Geiger Counter and a small bit of radioactive material. At any given moment each atom in the radioactive material has a certain probability of decaying. If, for instance, it’s a bit of 210Polonium, the half life is 138 days. This means that statistically, if you have a bunch of atoms of Polonium, half of them will decay within 138 days. The thing is, statistics doesn’t require half the atoms must decay. It could be that more decay or that less decay. It’s just a probability.

If I flip a coin a bunch of times, I should get heads half the time, but it doesn’t mean I will.
Now if my bunch of Polonium happens to add up to 138 atoms, statistics say that on any given day, I have a 50/50 probability of one atom decaying. So, imagine I have a cat in a box with 138 atoms of Polonium, and I have a Geiger counter to detect if any atoms actually decay. Just to make things interesting, I attach a vial of poison to the Geiger counter, such that if some atom decays, the Geiger counter will trigger and burst the poison, killing the cat.

According to Quantum Mechanics, the atoms each exist at every moment in both a decayed and a not decayed state. Only at that philosophically painful moment when the atoms are observered do the wave function collapse, and the atoms become absolutely decayed or absolutely not decayed. This means, until observed those atoms hover in the decayed/not decayed state and the cat hovers in both a state of alive and dead.

In all reality, the cat is a perfectly good observer of its own death. But still, the atom could be decayed and not decayed the Geiger counter or something else cames along to interact with its wave function and observe the outcome.

Radioactive decay isn’t the only weirdly probabilistic thing we observe. For instance, if I have the world’s most pathetic laser and it gives off just 1 photon at a time, and I point my pathetic laser at a series of slits, the photons will go through and scatter out onto a screen on the far side of the slit. If I keep watching where the photons have landed for a period of time, they will build up a pattern that just happens to be identical to the interference pattern that you get if a bunch of photons from a very bright source all going through the slits at once. Thus, for several odd quantum mechanics reason, photons have some weird probabilistic way going through slits as waves and interacting in probabilistic ways. While no one can predict where any one photon will land, using quantum mechanics we can predict the pattern lots of photons will build up.

But why should any one photon do one thing, when in the exact same situation another photon does something totally different?

But why should any one photon do one thing, when in the exact same situation another photon does something totally different? According to what is called the Oxford Interpretation or the Many World’s Interpretation, each photon actually takes every single different option, but each option occurs in a different, parallel, branching universe. Every time a choice is made, the universe branches. In this way, every possibility that could happen, does happen, just not necessarily in the universe we know as the one we live in. It also means that if I make it through this talk in this universe, in some other universe my computer self destructs, and in some other universe my car broke down on the way here. Everything that could happen, does happen, somewhere.

In this way, every possible value for every possible factor in our universe is played on in some parallel universe.

The question is, how do you test this Quantum-based multi-universe theory?

Unfortunately, the only way that has been defined really only tests the theory for the poor person running the test. Imagine the poor person who places a radioactive decay triggered gun at their head and steps into a box and waits to see if the world ends. With each moment the gun doesn’t fire, the world splits into a world in which the scientist dies, and a world in which she lives. If she continues to live beyond what statistics say is reasonable, than probability weakly claims that there should be other universe’s where the scientist has died. It’s a weak argument. It’s an a moral experiment, but… It’s at least one test we have the technology to do, even if no one will, I hope, ever do it.

Other methods are also being proposed, but we’re not in a position to run those experiments – the technology isn’t there. Perhaps in time, but not today.

So, while this theory is built on experimental results, and conforms to past experiments, it doesn’t make any useful predictions. In many ways, this theory, like string theory, is a nice bit of pretty mathematical art that might be true, but we really have no way of proving.

But quantum mechanics isn’t the only way to get at multiverses. According to Andrei Linde (of Standford University) and many others, it is possible that the field that drove the early period of inflation didn’t act the same way in all places. What if in some some places expansion continued, with fluctuations in the inflation leading to bubble universes expanding one from another extending on forever?

This “what if “ is layered on top of detailed theories that match our observed universe, and elegantly explain how inflation could have occurred. The multiverse falls naturally out of theories that drive the period of inflation with a (scalar) field that reacts to it’s environment. The early universe was filled with bubbling quantum fluctuations that acted like waves. As the universe expanded, the waves froze. The largest fluctuations froze first, and as the universe expanded, stretching the small waves with it’s growth, they eventually reached sizes where they also froze. Now, when waves interact, they can enhance one another or cancel one another. Depending on where you are sitting in this room, you hear my voice as louder or softer, depending on how the sound waves interact. In places, the interacting waves enhance my voice, and in the early universe, the waves in some places interacted to enhance the expansion.

In these spikes of chaotic inflation, new bubble universes could form, each growing out of a bit of the universe before it, each branching growing bubbling with it’s own physical characteristics. These universes can sprout out of one another nearly forever, and some theories suggest there could be 10^10^12 universes sitting along side one another, and in some cases branching off of our own universe. That’s a 1 followed by a trillion zeros of branching universes.

But, while this theory conforms to observations and explains what we experience, we currently have no way of knowing if it is true. Again, we have left the realm of testable science.

It seems, that with today’s technology and physics knowledge we must at a certain level label the first moments of the universe with the warning “Here be dragons.” We don’t know what set our universe in place, we don’t know why we are in a universe so precisely tuned to allowing life to exist. We have ideas, but… But ideas aren’t answers.

So this leaves us in a queasy place. In talking about the subject of this talk with my peers at SIUE, several put forward emotional opinions on what they want to be the truth. We all have our emotional feelings. But as a scientist, I look at untestable theories and have to say they really can’t be proven to be any more valid than Stephen King’s parallel universe series, the Dark Tower, in which there is one true universe and infinite child universes, with alternate, not real pasts and futures.

In this book, one of the characters, at the moment of his death, says “Go, then. There are other worlds than these…” In these words he propels the main character, the gun slinger to other truths, other possibilities, and other places in time and space. I don’t know if there are other multi-verses, parallel to this one, but I know our reality is not uniquely dictated by physics as we know it today. Our life in our universe is frighteningly improbable, and yet none the less real. Science doesn’t offer all the answers, but it does offer questions and a set of rules by which we can seek the answers.

For now, we are faced with three possibilities: Perhaps there is underlying physics that dictates our universe be one that allows us to be here. If that physics exists, I hope someone finds it quickly. Perhaps we live in some sort of a multiverse. If that is the case, I hope some experiments to test that possibility are defined soon. And, if it was a higher power that tweaked the parameters, I really hope he created some underlying physics that we can study and use to end at least this one line of questions while we open up many more. Science doesn’t answer the more fundamental questions of why does our universe exist and why is our universe the way that it is. All we can say is at the moment of the Big Bang, there be dragons.

    I really enjoyed your speech. It’s a great overview of where we are today and how we got there. Physics really adds to the whole picture and it’s intriguing to realize how much we don’t know. I am reading “The Trouble with Physics” by Lee Smolin and the ideas you discuss are along the same lines as he suggests in this book. The concept that modern physics holding out ‘string theory’ as the unified theory and that it’s acceptance is a norm even though there is no testing to verify its hypothesis raises interesting questions about how this thinking might impact modern views on general astronomy, inflation, dark matter, and infinity. When one asks what is ‘string theory’, it seems like since there is no clear mathematical model (at least for most mortals) and no clear or generally accepted description of it, it makes its ‘probability’ of being the unified theory in doubt. There seems to be a lot of missing information in both quantum mechanics and relativity theories, much as there is a lot of missing information about dark matter, cosmology etc. Is scientific theory changing to something beyond what has been used in the past? Very thought provoking.

    I know neon and argon, but what’s Xeon? I’ve never heard of that element before.

    This is a good speech, she is able to encapsulate many, many important ideas in a very concise manner.

    That does not mean there is not a logical breakdown in parts of the structure: Increasing the space between objects in a copy enlargement requires energy; and inflation does not have a (gravitational) energy budget for enlarging the space between objects. This is a thermodynamically bankrupt conjecture that should not be sold as an incremental improvement in our understand of the physical universe.

    I give up. The file has extension m4a, which is Real Audio, but RealAudio doesn’t recognize it. The text says it’s an MP4, but changing the extension to MP4 doesn’t allow Quicktime to play it.

    We will look at the theories of evolution in their two main foundations: the expansion of the universe, and the quantum or microorganism. To understand it with reason,thee first subject we are confronted with is God.Let us read a few verses from the Bible. Psalm 14:1 of the Old Testament says, “The fool has said in his heart,/There is no God.” This sentence may also be translated as “The fool does not want God in his heart.” The result of saying this can be found in the second sentence of the same verse: “They are corrupt; they do abominable deeds.”Let us also take a passage from the New Testament. Hebrews 11:6 says, “For he who comes forward to God must believe that He is.”THREE KINDS OF People Whether you claim to be a Christian, a non-believer, or a seeker after truth, we will start by examining the subject of God. In this respect the world is divided into three camps. The first is that of the atheists who do not believe in a God. The second consists of the agnostics. They have no sure knowledge about the deity. On the one hand, they dare not say there is no God, but on the other hand, they are not clear if God does exist. We belong to the third category of those who believe in God.

    Prosecution Is there a God? I will not try to say yes or no to this question. Rather, I will make this place a law court. I will ask you to be the judge, and I will be the prosecutor. The work of a judge is to make decisions, to approve or disapprove the truth of statements; the work of a prosecutor is to present all the evidence and arguments that he can possibly therefore we proceed, we have to be clear about one fact: all prosecutors are not eyewitnesses of crimes. They are not policemen. A policeman may personally witness an event, whereas a prosecutor obtains his information only indirectly. He places all the charges, evidence, and arguments collected before the judge. In the same way, I shall present before you everything that I can possibly find. If you ask whether I have seen God or not, I would say “no.” I am reading or demonstrating what I have gathered. My job is to search for facts and to call for witnesses. You are to arrive at a conclusion qualification people assert that there is no God. As a prosecutor I ask you first to check the qualification of these people. Are they qualified to make such claims? Are those who assert that there is no God moral or immoral? Do not just listen to their arguments. Even robbers and swindlers have their arguments. Of course, the arguments support them as robbers and swindlers. The subject of their arguments may be very noble; they may talk about the state of the nations and the welfare of society, but their opinions cannot be seriously considered. They are not worthy of passing such judgments. If a man is upright in his conduct and moral judgment, we can give credibility to his words, but if not, his words lose their credibility. This is especially true when it relates to the question of deity. It is interesting to note that the moral standards of men are directly related to their concept about God. Those who admit their own ignorance have a passable standard, while insistent atheists invariably have a low level of moral responsibility. I do not claim to know all atheists, but of the several thousand that I know, none of them possess a notably commendable morality. You may tell me that there was once a moral atheist, but if there was one, he is dead. Or you may tell me that there will be a moral atheist, but whoever he may be, he is not here yet. At least we can say that for now, we do not know a moral atheist ATHEIST IS Moral Once at a gathering at the University of Nanking, I remarked that no atheist is moral. There were many students on the campus who did not believe in God. They were greatly offended by these words. The next day, while I was speaking, they came and shuffled their feet in an attempt to distract me and the audience. The next day when they came again, they made funny gestures and faces at me and carried on continuously throughout the speaking. On the fourth day the vice-president of the university, Dr. Williams, came and said to me, “We had better change the place of meeting. These students are infuriated by your assertion on the first day that atheists are not moral. Today they are not going to use their feet and lips only; they are going to use their fists. I heard that they will be waiting at the entrance of the hallway and will jump on you when you step in.” I went along with the arrangement and conducted the meeting at another place. On the way to the meeting I walked alongside many students and listened to their conversations. Although many did not agree with me and felt uneasy about my preaching, they wanted to come back. One among them remarked, “Mr. Nee said that people who have no God have no sense of moral responsibility. This is perfectly right. How can anyone with moral decency shuffle his feet and jest while others are delivering a speech? Yesterday they caused such a disturbance in the meeting, and today they are going to come to fight. This is surely not what an honorable person would do. There is no doubt that those who do not believe in God do not have moral decency. Let us go to the meeting regardless of what they plan to do.”Once a young man told a preacher, “When I was young, I seriously believed in God. But now that I am in college. I can no longer believe in Him.” The fifty-year-old preacher patted the young man’s shoulder and said, “My son, you do not believe in God anymore! Let me ask you a question: Since you have been converted to be an atheist, have you advanced morally? Has atheism helped you become better? Has it made your thoughts cleaner or your heart purer? Or did it make you just the opposite?” That young man felt ashamed. He admitted that he had gone downhill morally since his denial of God. The preacher pressed on: “I am afraid that you are not really saying that you believe there is no God, you are just hoping that there is no God.”
    DO NOT JUDGE ACCORDING TO
    Hope
    Many people are not really convinced that there is no God; they merely hope so. They would rather that there were no God in the universe. For them it would be much more convenient in respect to many things. I myself was one of those people. When I was a student I claimed that there was no God. Although I was extremely strong in my claim, something within me seemed to be protesting and saying, “There is a God.” I knew deep in my heart that God exists. But my lips refused to admit this so that I could have an excuse for sinning. By declaring the nonexistence of God, going to sinful places was justifiable. If there were no God, I would become bold to sin. When you believe in God, you dare not do certain things. When you do away with God, you feel free to commit the worst sins without any fear whatsoever. If you sincerely hope to raise your moral standard by asserting the nonexistence of God, then your arguments are still plausible. However, the only reason men claim that there is no God is for an excuse for lawlessness, immorality, license, and indecency. For this reason, their whole argument is not worthy of consideration. The question is, “Are you qualified to claim that there is no God?” If your hope is merely for an escape from justice, you have lost your ground already
    MAN THE GREATEST?
    One day a young man came to me and said, “I do not believe in a so-called God. Man is the greatest. He is the noblest among all creatures. There is no God in this universe; man is everything.” We were sitting opposite each other. After hearing what he said, I stood up, went to one side of the room, stooped down, and gazed at him intently. I said, “You are really great!” Then I walked to the other side of the room and looked at him from another angle. “That is right,” I said deliberately; “You are great! In Kiangsu province there are thirty million who are like you. There are at least four hundred million of your kind in China. The world contains only two billion who are the same as you are. Do you realize that during the last few days there has been a flood in the south? The dykes along the river are in jeopardy. The whole population in Hsing Hwa with more than two hundred thousand people have been recruited and rushed to the dykes in a panic. They are carrying earth with them to reinforce the banks. The repair work is still going on.”Suppose that the world is recruited to hollow out the sun. A hole is drilled through the surface, and everyone has to remove a load from the inside. Assuming that no one will be burned to ashes, do you think that they can do the job? Even if all the people themselves were inside, they would not fill up the sun. That is not all. If you put several hundred planets the size of Earth inside and started shaking it, you would still find that the sun would be very empty inside. How many suns are there in the universe? Do you realize that the number of solar systems is in the hundreds of millions?”HOW VAST IS THE UNIVERSE?I then said to the young man, “And here you are! You have not even walked through the whole earth, and yet you consider yourself greater than the whole universe. Let me ask you, do you know how vast the universe is? Take light for example. Light travels at 186,000 miles per second. Try to calculate how far light travels in one minute, or one hour, or a day, or a year. There are some stars whose light takes three thousand years to reach us. Go and work out how far they are from us! And you think you are so great! I would therefore advise all atheists and young men alike to admit the incompetency of man not only morally, but intellectually and academically as well.”CAN MAN EXTEND BEYOND THE BOUNDSOF TIME AND SPACE?Another time when I was in Kaifeng, I met another one of those young, stout atheists. I walked up to him and patted him on the shoulder, saying, “I saw God today!” He stared at me in curiosity and demanded a further word. I replied, “You are God! If you know that there is no God, then you have to be God.” He asked for an explanation. I said, “Since you are convinced that there is no God, you must have traveled over the whole earth. If God is not in Shanghai, He may still be in Nanking. You must have been to both places. That is not all. If God is not in Nanking, He may be in Tientsin. You must also have been to Tientsin. But you cannot draw this conclusion simply by being in China; God may be in another country. So you must have been to every country on this earth. If God is not in one place, He may be in another. Therefore, you must have traveled throughout the world. One never knows if God is hiding at the North Pole or the South Pole, or in the woods or wilderness somewhere. So you must have combed through all those regions as well. If God is not found on earth, He may be found on the moon. You therefore must have been to the moon. God may also be on other planets or in outer space. This means that you have traveled through space and all the other galaxies as well. If you can say that there is no God, it must mean that you have traveled throughout the whole universe. If this is the case, you must be God yourself.”This is not all. Even though you know that God does not exist in Shanghai today, how about yesterday? Perhaps God will come tomorrow. You say that you know there is no God today, but what about last year? And how do you know that God will not come next year? You say that there is no God this year, but what about a thousand years ago? Very well, you must be an everlasting one who knows everything about the past and future. You have to be a being beyond time and space. You must be in Tientsin and in another country at the same time; you must be omnipresent from the east to the west, from the North Pole to the South Pole. Who else but you can be the very God? If you are not God, you can never be qualified to say that there is no God.”THE Evidence Some will immediately step back and say, “I have never said that I know there is no God. One can never tell whether there is a God or not.” Well, if you cannot give a conclusion, I will ask witnesses whom I consider trustworthy to present arguments to you and prove the existence of God. Again let me say this, you are the judge, and I am the prosecutor. I am presenting only the evidence before you. Decide for yourself if there is a God.
    THE Universe First, look at nature, the world that is before our eyes and every phenomenon in it. We all know that scientific knowledge is the rational explanation of natural phenomena. For example, there is an observed drop in the temperature of a patient. The drop in temperature is a phenomenon, and the explanation for it is scientific knowledge. When an apple falls from the tree, it is a phenomenon. Why does an apple not fly into the air? The explanation for this phenomenon constitutes knowledge. A man with knowledge is a man who has the proper explanation TWO Explanations The universe displays countless phenomena of diverse forms, colors, shapes, and nature. We cannot fail to notice these phenomena before our eyes. The explanation for all these phenomena is known as knowledge. All thoughtful persons have only two explanations as far as the origin of the universe is concerned; there is no third explanation. You have to take one or the other of them. What are these two explanations? The first says that the universe came into being through natural evolution and self-interaction; the second attributes its origin to a personified Being with intellect and purpose. These are the only two explanations presented by all philosophers of the world. There is not a third anywhere did the universe come from? Did it come into existence by itself or through chance? Or was it designed by the One from whom we derive the concept of God? You have to think and then make a decision about it. Everything that is by chance has certain characteristics. I would suggest you list all of these in a detailed way, the more the better, and then compare all the phenomena of the universe with your list. Alongside of this make another list of the characteristics which, in your opinion, would be prominent if the universe were created by an intelligent Being. Now by a simple comparison of nature with your two lists, it will be easy to draw a reasonable conclusion Events What are the characteristics of things that come about by chance? First, we know that they are unorganized. At the most they can be partially integrated. They can never be totally organized. One can achieve a specified goal by chance once, but he can never achieve a specified goal by chance all the time. Anything that comes together by chance can only be integrated partially, never totally. For example, if I throw this chair to the other side of the room, by chance it may come to rest at a perfect angle. If I do the same with a second chair, it may also lie neatly beside the first one. But this will not keep on happening with the third and the fourth and so on. Chance can only provide partial organization. It does not guarantee total integration. Furthermore, all random interactions are aimless, disorganized, and purposeless. They are without order and structure; they are loose, formless, disorderly, and not directed toward any meaningful purpose. Briefly, we can say that the characteristics of chance events are disharmony, irregularity, inconsistency, purposelessness, and insignificance. We will write down these four characteristics on our consistency AND Organization Now let us compare the things in the universe with these characteristics. Take, for example, the human being. He is carried in his mother’s womb for nine months and delivered; he grows up and eventually dies. This cycle is repeated for every single individual. Consistency can be observed. It is not a wild game of chance. Again, look at the sun above your head. It does not exist purposelessly. Rather, it has its purpose and significance. Look at the moon, the stars, and the myriads of galaxies through your telescope. Some stars have their own planets. They all follow definite tracks and patterns. They are all organized. Their manner of motion can be calculated and predicted. The calendar in your hand is derived from them. Even next year’s calendar can be printed before this year is past. All these show that the universe is organized, consistent, and microorganism us turn to the micro-world. Take a thin slice of wood. Put it under a microscope and observe its grain and structure, all meticulously regular and rhythmic. Even a blade of grass and the petal of a flower are finely fashioned. Nothing is unorganized or confused. Everything is disciplined and functional. All these things witness one fact to you: the universe, with its macro and micro aspects, is purposeful and meaningful. Can you say that all these came into existence by chance? Surely you cannot IT OCCUPIED?Once I was preaching the gospel with a co-worker of mine in a village. On the way back we were extremely thirsty. There was neither a teahouse nor stream for us to get water. In fact the whole area was uninhabited. After walking for a while we came across a thatched hut. We went to the door quickly and knocked. For a long time there was no answer. We thought that no one lived there. When we opened the door and went in, we found that the floor was swept clean. In one of the rooms was a bed with nicely folded sheets. There was a teapot on the table, and the tea in it was still warm. I said, “Surely someone must be living here. All the arrangements indicate beyond doubt that this place is occupied by someone. We should not drink this tea. We must get out quickly or else people will think we are thieves.” We walked out and waited for the owner to return. By observing the arrangements of the house, we concluded that someone was living there, without having seen the occupant. In the same way, we know that God is there by the arrangement of everything in the universe, although we cannot see Him. Every single phenomenon of nature is so balanced, organized, meaningful, and functional. You may say that they come by chance, but it is impossible for me to believe that chance is its sole originator. The Bible says, “The fool has said in his heart,/There is no God.” Only foolish people can say in their hearts that there is no God.
    CHANCE OR Design
    The universe has to be created by Someone with profound wisdom, vast knowledge, and intricate design. If you cannot accept the concept of random formation of the universe, you have to admit that it was created by such a God. There cannot be a third explanation. The choice is left to you. You have to decide if the universe came by chance or whether it was created by God.
    A DEMAND AND ITS Object
    One witness may not be enough. I will call in another. This time we will consider man’s heart. Before doing so, we should also observe one fact: wherever there is a desire, there must first be an object for that desire. For example, an orphan who has never seen his father naturally has a desire for a kind of paternal love. I have asked many people who were orphans, and they all have felt this irrepressible yearning. By this we can see that every desire of the heart arises out of an object in the worldwide human beings we have a need for social belonging. We need companionship and mutuality. If you put a boy on a deserted island and he grows up alone, he still has the yearning for companions, for beings like himself, even though he has never seen a human being. This yearning or desire is the very proof that somewhere in the world there is something known as “man.” At a certain age, man begins to think about posterity; he starts desiring children and grandchildren. This is not a mere fantasy. This desire stems out of the existence and possibility of offspring. Hence, where there is desire, there is an object for that desire.
    THERE IS GOD IN THE Heart Do we have any desires other than social identity and self-propagation? What other cravings do we have? Deep in everyone there is a craving for God. Whether they are highly civilized races, such as those among the Caucasians, or the ancient civilizations, such as the Chinese civilizations, or the African natives and uncultured aborigines, they all have a common craving –God. As long as they are men, they have a yearning for God, no matter what race or nationality. This is a fact. You cannot argue against it. Everyone is seeking after God. Everywhere man is craving for God. This is very clearway applying the principle that we just mentioned, we can see that since our heart feels the need for a God, there must necessarily be a God in the universe. Since there is a need for God in the heart, there must be the existence of God in the universe. If no God exists, we would never have such a craving in our heart. We all have an appetite for food. In the same way, we all have an appetite for God. It would be impossible to live if there was only an appetite for food but no food. Likewise, it would be impossible to live if there was a capacity for God but no God.
    NEVER THOUGHT ABOUT GOD?Once an atheist rudely rebuked me in a loud voice: “You said that a man has the psychological need for a God. But there is no such thing, and I do not believe in it.” I said, “Well, do you mean to say that you never think about God? In fact, even while you were talking, you were thinking about Him. This indicates that you do have a capacity for God. There is no one who has never thought about God. He may try not to think much about Him. Since this thought is in you, there must be such an object outside of you.
    “THE WORDS AND THE HEART
    A young man once came to me to argue about God. He was vehemently against the existence of God. He gave me one reason after another for saying that there is no God. As he was enumerating the various reasons why God should not exist, I listened to him quietly without saying a word. Then I said, “Although you insist that there is no God and support yourself with so many arguments, you have lost your case already.” He said, “What do you mean?” I went on to explain: “Your mouth can say as much as you want about there not being a God, but your heart is on my side.” He had to agree with me. Although one can give all sorts of reasons in the head, there is a belief in the heart that no argument can defeat. A stubborn person may give a thousand and one reasons, but you can have the boldness to tell him, “You know better in your heart that there is a God. Why bother to look for evidence outside?”Now what would you say? After looking at nature and the universe, after checking with your inner feeling, it is up to you to decide whether or not there is a God. But you should not be irresponsible; your attitude must be sober because everyone has to meet God soon. One day you will all stand before Him. Everything concerning yourself will be laid bare. On that day you will know God. But now is the time for you to be prepared. We should all be prepared to meet our God.
    I shall begin by assuming that the issue of God’s existence is settled. We all believe that there is a God. As those who desire to know the truth, we must go one step further to find out what kind of God He is. God is the greatest Unknown. We must spend some time to find out about this unknown One. The next step now is to know what kind of a God He is.

    In the past few thousand years man has been inquiring about the nature of God. Is He kind or is He righteous? Is He indifferent towards us, or is He extremely interested in human affairs? These types of questions are the direct cause of all human religions. What is religion? Religion is man’s inquiry about God and his explanation of Him. Through these explanations, different men have arrived at different concepts about God. What kind of God is He? This is a big question. It is also a very serious question. We have all given our thought to this subject at one time or another. The question might even have occurred to our little mind when we were five years old. All men, educated or ignorant, have been intrigued by this question. It comes naturally after some contemplation and observation.

    But a person trying to speculate about God is like an ant attempting to understand a human being. It is extremely difficult for the little creature to try to realize our life, nature, and mind. In the same way it is impossible for us to try to comprehend God. For this reason, in the past few thousand years, all kinds of people, theologians and philosophers alike, have done much thinking about Him. What has God been doing all this time? Has He been indifferent to us or has He tried to reveal Himself to us? What is God’s attitude? Do you think He would say, “I am God and have nothing to do with human beings. I do not care what you think about Me. I shall stay in heaven as God. Let the mortals be ignorant!” Or do you think He has a desire to reveal Himself to man and visit him?
    When I was in India, I saw some people lying naked on beds studded with nails. Some walked with bare feet on burning coals. These people devoted a great deal of energy to seeking after God. What has God done to them? Did He hide Himself and take no notice of them at all? Has He not kept Himself as a perpetual mystery? This is a great question. We have to consider it scientifically and objectively in order to find out what God is like.

    A few years ago I spoke on a similar subject to some medical students in an auditorium in Cheloo University. I said that man is an organism with a life. God also is a life. Man’s life is higher than that of the lower animals, and God’s life is even higher than that of man. I asked the students, “Since we realize that all living organisms have some common laws and express some common traits, can you name them?” Different ones then started to bring up different points. At the end we summed up the discussion in this way: all living organisms contain two common characteristics. You can call these characteristics their common expressions or their common laws. First, every life wants to preserve itself. It tends to reproduce itself. There is the ability to produce posterity, to continue its own life. Second, every life wants to have fellowship with other lives. It cannot stand being by itself. When a man cannot find fellowship with another human being, he goes to dogs, cats, fish, or birds and makes friends with animals. All living creatures desire fellowship.
    Based on these two characteristics of life, namely, the preservation of itself and fellowship with others, laws of human government are instituted. For example, the death penalty reflects a convicts desire to preserve his own life; punishment comes in the form of taking away and terminating such a life. This is the way to inflict suffering on a life. Imprisonment, as a less serious punishment, cuts him off from having fellowship with others. This reversal of the life principle becomes then a suffering for him. From this we see that punishment is applied according to the principles of life.
    With these two chief characteristics in mind, let us turn to the life of God. God is an organism of a higher order than human beings. He is naturally governed by this law of life. We can know God by the characteristics and distinctive features of His life. From this we can deduce whether or not God wants to have fellowship with man.

    There are two kinds of religion: religion based on natural concepts and religion based on revelation. Natural religion starts with man as the center. He is the one that is seeking after God and studying about Him. What then is revelation religion? Revelation religion comes directly from God. He is the One who comes to reveal things to us. Man’s thoughts are often useless fancies. God’s revelation alone is trustworthy. Christianity is different from all other natural religions in that it is a religion that comes from revelation. Christianity begins from God. It is God who comes to seek out man, rather than man who seeks after God.
    I will not try to persuade you to believe in Christianity or to read the Bible. I will only make a few suppositions. We will treat the subject in the same way as if we were solving a problem in geometry. We will start from the suppositions and then deduce our arguments step by step. We will examine our reasonings to see if they are sound and if our conclusions are logical. As in mathematics, with some problems we work forwards, while with others we work backwards. At any rate, in the end we should be able to tell whether or not a supposition is justified.

    We have to make a few suppositions. The first one is that God exists. This in fact has been covered by us already. We have agreed that there is a God. He is a Being who has a purpose.
    Second, we assume that God has a desire to reveal Himself to man. If God wants to reveal Himself to man and if He wants us to know Him, how does He do it? In what manner can He be made known to us? If He speaks to us through thunder or writes to us through lightning, we will not be able to comprehend His message. How then does God make Himself known to us?

    If He is to reveal Himself and if He wants us to know Him, He necessarily must do it through human means. What then are the common ways that men communicate with one another? First, they do it through speaking and second through writing. All means of communication, whether telegraph, telephone, sign, or symbols, are all included in these two categories. If God is to manifest Himself, these are the only two means for Him to do so. For the present we set aside the aspect of speaking; we will see how God communicates with us through writing.
    If God reveals Himself through writing, of all the volumes written by different people throughout the centuries, there must be one book which is divinely inspired. This is a very crucial test. If such a book exists, it proves not only the existence of God, but it contains His written revelation to us as well. Is there then such a divinely written book?
    In the search for such a book, let us first mention a few basic principles. Suppose I want to order a book from a publisher. If I can tell him the name and author of the book, there will be no trouble getting it. If, however, I forget the name and author of the book, I can describe the characteristics of it to the publisher, such as the contents, size, color, binding, etc. The publisher will then search through all his books and locate the volume I want. God has one book in this universe. How do we find it? We have to know its characteristics first. If there is any book that has been written by God, it must meet certain conditions or have certain qualifications before one can say that it is from God.

    Let me put forth a few propositions. If there is a book written by God, it must first of all mention God. It must tell you that it is from God and that its author is God. This is the first qualification. Second, it must carry a moral tone that is higher than what we commonly know. If it is a fabrication, it can at the most be on the same level as man. Third, if there is such a divine book, it must tell us about the past and the future of this world. Only God knows clearly what occurred in the past and what will happen in the future. Only by telling us these matters will we know Him as God. Fourth, this book must be simple and available so that all may be able to secure and understand it. If there were only one such book in the world, then only a very few people would be able to see it. It would not pass the test unless it is a book accessible to everyone. In the United States there is a group of people who claim to have a book from God. It is engraved in gold and contains only twelve pages. Such a book then would not be accessible to the Chinese. God would never write to us a book at which we could not look.
    Now the matter is simplified. Let us repeat these four conditions once more. (1) If such a book exists, it must tell us explicitly that its author is God. (2) It must carry a high tone of morality. (3) It must give a detailed description of the past and the future of the universe. (4) It must be available. Let us pick out some of the more important writings throughout human civilization and check them against these qualifications to see if any meets our requirements.

    We will start from books that are generally considered to be good. Let us take the Chinese classics of Confucius. They are immediately disqualified under the first requirement, for none of them claims to be written by God. They do have a high tone of morality, but they fail to give the origin and destiny of the world, the universe, and man. This does not mean that they are worthless books; it means that they do not contain the qualifications we want. They are not what we are looking for.
    Let us go to the classics of other cultures. There are numerous volumes of famous writings, but none of them passes the first test. They are all clearly written by man. They may be masterpieces in philosophy or morality, but they are not written by God, nor are they divinely inspired. We have to set them aside.
    There is a book in India called the Rig-Veda. It once dominated Hinduism. However, it does not claim to be written by God.
    Another book called the Avesta, written by a Persian named Zoroaster, is also extremely influential in the Middle East. It does not claim to be from God either. Moreover, its moral tone is not especially commendable.
    Let us come to the Koran of Mohammedanism. This is the closest one we can find. It tells us that it comes from God; it meets the first requirement. However, it does not fulfill the second requirement, for its moral tone is too low. The heaven it describes is full of lusts and flesh. God could never write a book with such licentiousness and immorality. Hence, this book does not pass the test of morality.

    After searching through all the books, you have to come finally to the Bible. If God desires to communicate with man, and if He does so through writing, then this is the only book that can pass the four tests. Hence, this must be the book God has for man.
    What does this book say? In the books of the law in the Old Testament, it says, “Thus saith the Lord,” at least five hundred times. Other books in the Old Testament repeat the phrase about seven hundred times. In addition to the references in the New Testament to the speakings of God, the Bible has more than two thousand claims of divine origin. If God has no intention of communicating with man, we can forget about this book. But if He does communicate with man through writing, then this book has to be of immense value. Can you find another book where God is claimed as its author that many times?
    We have to see if the Bible meets the second qualification. Let us take a look at its moral tone. Everyone who has studied this book confesses that it carries the highest moral standard. Even the sins of the most noble persons are recorded and condemned without mercy. Once a strong opposer of the Bible was asked by his son, “Why are you so strong against the Bible?” He answered, “If I do not condemn it, it will condemn me.” This book does not let us get by easily. The human concept is that all sexual acts outside marriage are considered as fornication. The Bible, however, says that even an evil thought is fornication. Human morality condemns an act of killing as murder, but the Bible condemns a slight hatred in the heart as murder.
    We consider a man who lets his enemy get by without paying vengeance as forgiving. But the Bible charges man to love his enemy. How high is its moral tone, and how low we are before its standards! You cannot help but admit that it presents the best ethical code for humanity.

    Furthermore, this book describes in detail the past and future of the universe. Once a friend told me that he could believe in everything the Bible says except the parts in Genesis and Revelation where it talks about the origin and destiny of the heavens and earth. I told him that if this is indeed a book from God, it must, of necessity, contain these matters. If the Bible did not contain Genesis and Revelation, it would be the same as any other book, and we would have to look for another book; it would not be the one we want. But the past condition of the world and its future destiny are recorded here. Hence, the third qualification is also met.

    What is the circulation of such a book? Last year (1935), more than two hundred million copies were sold. Can you name another book that has such a high circulation rate? This statistic, moreover, is not limited to just last year; every year the number has remained approximately the same. In one sense this book is very popular. In another sense it is like a thorn in your hand; it pierces you. This book gives you a headache. It creates an unspeakable uneasiness within man. It even causes man to oppose it. In spite of this, its annual sales are still over two hundred million.
    Furthermore, this book is translated into more than seven hundred twenty languages. In every country and among every race, there is a translation of this unique book. It is extremely easy for anyone to obtain a Bible anywhere in the world. If the Rig-Veda were God’s book, then more than half of the world would perish due to a failure in obtaining it. Even if you put the Rig-Veda in my hand, I would still be unable to understand it. If only the educated ones can contact God, then I am destined to go to hell. If only the Indians have the opportunity, we Chinese, as well as other races, are out of hope. If God speaks through the Rig-Veda, then where can we find that book? Maybe we can only find the original copy in the London Museum. And even that may not contain the original meaning of God’s revelation to man.

    This is not all. The Bible contains sixty-six books and it is divided into the Old and New Testaments. It was written by no less than thirty people. The span from the time the first book was written to the time when the last book was finished is more than sixteen hundred years. The places where they were written are also different. Some were written in Babylon, some in Italy, some at one end of Asia Minor, others at the other end of the Mediterranean. Furthermore, the writers themselves differed in their backgrounds. Some were lawyers; some were fishermen. There were princes, and there were shepherds. All these writings by men of different backgrounds, languages, environments, and periods are put together. The amazing thing is that it is still a complete book.
    All those who have had some experience of editing know that in order to put together a few articles written by different authors, it is necessary for the authors to be of comparable level of academic achievements and viewpoints. Even when the academic standard and viewpoints are similar, there will still be conflicts and contradictions when you put five or six articles together. But the Bible, though complex in contents, contains history, poetry, laws, prophecies, biographies, and doctrines and was written by so many different ones at different times and under different circumstances, yet when you put them together, they surprisingly run as one continuous volume. There is no conflict or contradiction. They are written in one breath.

    If you read this book carefully, you have to admit that God’s hand is behind all the writings. More than thirty people of varied backgrounds and ideas in different times and places wrote these sixty-six books. When you group them up, they link together as if they were written by one individual. Genesis was written about fifteen hundred years before Christ, and Revelation was written ninety-five years after Christ. There is a time span of sixteen hundred years. One talks about the beginning while the other projects the end of the world. Yet whatever begins in Genesis is concluded in Revelation. This amazing feature cannot be explained in human terms. Every word of it has to be written by God through man. God is the motivating One behind the whole composition.

    There is another remarkable thing about this book. In itself it is a book that gives life. Yet countless numbers of people have lost their lives for its sake. There was a time when anyone who held this book in his hand would immediately be put to death. The most powerful empire in history was the Roman Empire. There was a time when this empire summoned all its forces to destroy this book. Everyone who possessed it would be inhumanly persecuted and later killed or burned. They wiped out thousands of people and burned countless copies of the Bible. They even set up a monument at a place where they killed Christians. On it was the inscription: “Christianity is buried here.” They thought that when they had burned all the Bibles and removed all the Christians, they would see Christianity lying there beneath their feet. But it was not long after that when the Bible came back again. Even in a country like England, which has already accepted Christianity as its state religion, you can still find tombs of martyrs for Christ if you visit different places there. Here and there you can find places where the Bible was once burned. Or you may come across a tombstone that tells you that such and such a person tried so hard and wrote so many books in his life to oppose the Bible. One place may tell you that the Bible was once burned there, and another place may tell you that Christians were once killed there. One signpost may point you to a statue of martyrdom, and another may point to a site of Bible burning.
    Why is it that so many people have tried so hard to oppose this book? Why is it that men would pass by other books, but would either oppose this book with every fiber of their being or would put their whole life to the stake for it? There must be something extraordinary here. Even if you do not believe that this is God’s word, you have to admit that there is something unusual about this book.

    This book seems to be very simple and easy. If you consider it from the historical point of view, it tells the origin of the universe, the earth, the plants, human beings, how they established their kingdoms, and how they will eventually end. This is all. There is nothing special about it. Yet it has been handed from generation to generation for centuries. Today it is still with us. Moreover, if you do not confess that it is truth, you have to conclude that it is false. You can disregard many books, but you cannot ignore this book. Nor will it ignore you. It will not let you go. It demands a verdict from you. It will not pass you by.

    Another remarkable thing about this book is that almost half of it is prophecy. Among the prophecies, almost half of them are fulfilled. The other half are for the future and await fulfillment. For example, it predicted the fate of the nations of Moab and Ammon and of the cities of Tyre and Sidon. Today when people talk about big cities, they mention London and Shanghai. Then it was Tyre and Sidon. They were two chief cities of the ancient world. The prophecies concerning these two cities were all fulfilled. Once I was in the Middle East. For some reason I did not visit those two places. However, I bought two pictures of those cities. It amazed me when I looked at those pictures. I could not help but believe in the Bible. It was prophesied that if these two metropolitan cities did not repent, they would be destroyed and devastated. Their land would become hills of rocks and pebbles where fishermen would come to dry their nets. In the pictures that I bought, there was nothing but fishing boats and open nets on the shore. This is only one small fact that proves the reliability of biblical prophecy.
    If you compare past events with the prophecies in the Bible, you will find that they all correspond one with another. For another example, take the birth of Christ. Isaiah prophesied concerning a virgin with child a few hundred years before Christ actually came. Later, He was born indeed of the virgin Mary. The prophecy was accurately fulfilled. As the prophecies concerning the past have been fulfilled, so the prophecies concerning the future must also be fulfilled.

    If God desires to communicate with man, He must do so through common human channels of communication. He must use the human language or human writings. In other words, there must be a book in the world that is a direct revelation from God. If such a book does exist, it must contain the four criteria we mentioned. Now we can say that such a book is found. This book tells us that God desires to have fellowship with us. He speaks to us through this book. Through it God is no longer an unknown Being. We can now know Him. This book is the Bible. I hope all of you will read it
    THIS IS A SERIOUS MATER, IS HE CRAZY? A LUNATIC?A LIAR? PLEASE YOUR VERIDICT.,
    God desires to reveal Himself to us. He does so through means that are comprehensible to man. These are namely written and spoken language. We have seen how God reveals Himself through writing. Now we want to take a look at His revelation through speaking.
    Suppose that you have had correspondence with a person for many years; however, you have never seen him. Naturally, you would want to know him more by having some direct acquaintance with him. Full understanding of someone cannot be achieved merely through writing. Direct contact gives a better chance. It seems as if communication through speech is of a more intimate and thorough nature than writing. When spoken language is added to written language, communication becomes enhanced. If you take away either of the two, you have a gap. Of course, if you take away both, communication is completely voided. Effective communication is always carried out by these two means.
    If God’s intention is to reveal Himself to us, He must of necessity do so through speaking. But how does God speak? Does He trumpet from the heavens? If so, we would all be frightened to death. We would all run away. No one would dare to listen. There is a chasm between Him and us. He, being so high and great, would drive us away from His holiness. How then does He speak?
    THE WINTER ON THE MOUNTAIN
    Let me relate to you a story. One winter I was staying on the mountain Lu-shan, recovering from an illness. It was immediately after the war, and there was practically no one living on the mountain. In the vicinity of my dwelling, one could hardly see anyone all day long. I am a quiet person by nature. This kind of environment was very appealing to me. Not only was it quiet there, but the weather was cold as well. From morning till dusk, all I saw was a boy who came three times to deliver my meals. At the beginning I was quite at ease. But after a while, even a person like me began to feel lonely.
    One day after lunch I went to take a nap. There was a balcony outside my bedroom window. When I woke up I saw some little creatures gathering around the balcony. Bits of my meal had been dropped there, and the birds were busily chirping around them. As they hopped around, they chirped and made many cheerful noises. I said to myself, “All right. Since I cannot find any human beings, I will try to make friends with these little birds.”
    I rose up and went out to greet them. But in an instant they all flew away. An idea came to me. I took some of the leftover rice and began to arrange it in rows, with only a few grains in the first row and gradually increased them towards the entrance of the doorway. I hid behind the door and watched them coming. Soon they gathered around again. I said to myself, “This is my chance.” I walked out and began to make friends with them. But the minute they saw me, they all scattered. Some perched on the branches of the tree across the balcony and stared at me, as if trying to determine what my intention was. Every time I approached them, they flew away, and every time I walked away, they came back. This went on a number of times.
    I wanted to preach to the birds. I wanted to tell them, “Little birds, I have no special intention in doing this. This is winter on the mountain, and food is scarce. I have enough food with me, and I just want to share it with you. Please be at peace and come down. I only ask that as you eat, I can sit among you. I want to listen to your songs and watch you playing. Come. Let us be friends…” But the birds would not come. They did not understand me. I had to give up.
    Later I had a certain realization within. I began to preach to myself. I said, “This body of mine is too big. If I could shrink from five feet eleven inches to the size of a bird, and even change myself into a bird, they would not be alarmed by my presence. I could then tell them my heart’s intention, and we could spend the winter on the mountain Lu-shan together.”

    We have a similar problem today. If God remained God, we could never understand Him. If He talked to us in His language, we would be altogether lost. If God wants to reveal Himself through speaking and have fellowship with man, He must shrink Himself to such a degree that He and we are the same. Only then would He be able to speak to us and tell us of Himself and of the mysteries of the universe. Only then would we be able to understand Him.
    Has God become a man to reveal Himself through His speaking? Let us again use the method of supposition. What if God revealed Himself through the human language? What if He became a man and fellowshipped with man? The implication is tremendous here! It would mean that in this world, among all the human beings throughout history, one person was not merely a man, but God as well! If it is granted that God became a man, there must be a mortal who was also divine. We need to find out about this One.

    This is a thorny task. But we will employ the effective method we have adopted—namely, setting down a few principles. Then we will search according to these qualifications and directions. We want to base our evaluation on what manner of life a person should possess and what qualifications he must have if he is God.
    The first condition that this person must fulfill is that he must claim to be God while he is on earth. He cannot be apologetic about it. He must declare boldly that he is God. Only then can we know who he is. Without this declaration, we have no way to guess his identity. Hence, a declaration is our first qualification.
    Second, the way this person came into the world must be different from ours. If I said that I am God and yet was born in the same manner as every other mortal, my words would carry no force. If on the other hand, I dropped down from heaven, my assertion would be taken seriously. The way this person comes into being must be extraordinary. He must come in an absolutely different fashion; otherwise, his words will not carry the necessary weight.
    Third, this man must bear a moral standard that is far above that of all other human beings. He must have God’s holiness, and his life must bear the mark of God’s righteousness. For example, if I became a bird and lived in exactly the same way as other birds, without showing them anything extraordinary, I could not convince them that I was actually a man. If God is to become a man, His moral behavior must be of the highest quality. This is the only way that we could identify Him as God.
    Furthermore, if a person is God, he must necessarily be able to perform things which no mortal can do. If he can achieve what we cannot achieve and know what we do not know, we can say that he is truly God.
    Lastly, this person must be able to tell us the divine purpose concerning man. What was God’s purpose in creating the universe and man? How does He take care of human pains and sorrows? What is the origin and ultimate solution of everything in the universe? What should our attitude towards God be? All these he must reveal to us. Unless this one shows us what we do not see, we cannot say that he has shown us any revelation.
    We will set down these five conditions and put the whole of humanity to the test. Let us find out if someone meets the five requirements. Such a person would surely be qualified to be God.
    The first person to put to the test should be yourself. Of course, you are not God, because you have never claimed to be God. Nor have I ever claimed to be. So that rules out you and me. Very well, now we will introduce Confucius. If you read his books, you will find that he did conduct a very moral and proper life. But he never claimed to be God either. Hence, he fails in the first step.
    What about Sakya Muni, the founder of Buddhism? Not only was there an absence of the claim of divinity, but his philosophy itself is void of deity. He did not believe in the existence of God. Since he had no God, he cannot be God either.
    Next, go to Mohammed. He believed in God. But he never claimed to be God. He called God Allah and himself the prophet of Allah. If you go through every person in history, you will discover that no one ever claimed to be God except One. That One was Jesus of Nazareth. He claimed to be the living God. No other person put forward such a claim.

    How can Jesus of Nazareth claim to be God? Before going on, we have to pause for a moment to seriously consider the matter. It is not a light thing to claim to be God. A person who makes such a claim falls into one of three categories. He must belong to one of these three categories; he cannot belong to all three. First, if he claims to be God and yet in fact is not, he has to be a madman or a lunatic. Second, if he is neither God nor a lunatic, he has to be a liar, deceiving others by his lie. Third, if he is neither of these, he must be God. You can only choose one of the three possibilities. If you do not believe that he is God, you have to consider him a madman. If you cannot take him for either of the two, you have to take him for a liar. There is no need for us to prove if Jesus of Nazareth is God or not. All we have to do is find out if He is a lunatic or a liar. If He is neither, He must be the Son of God. These are our three choices. There is no fourth.
    What did Jesus of Nazareth say about Himself? In John 10:30 He said, “I and the Father are one.” We need some explanation here. In the Bible the invisible God is called the Father. The Son manifests and expresses the Father. What is hidden is the Father, and what is expressed is the Son. The Son is the One who can be seen and touched. Behind, you have the Father. In front, you have the Son. The two are actually one. They are the two sides of the same reality. When we talk about two, we refer to the fact that one is hidden while the other is revealed. When we talk about one, we say that the revealed One is just the hidden One in manifestation. This is the biblical interpretation of the Father and the Son.
    Therefore, when Jesus of Nazareth one day said, “I and the Father are one,” it was a statement that no one else could make. This man was saying in reality that He and the invisible God are one entity. He is God and God is He. God is the invisible Father, and He is the manifested Son. The Father and the Son are one! Who can this One be that made such a claim? Is He a madman? Is He out to deceive us?
    After Jesus spoke such a word, what reaction do we see? “The Jews again took up stones that they might stone Him. Jesus answered them, I have shown you many good works from the Father; for which of these works are you stoning Me? The Jews answered Him, We are not stoning You for a good work, but for blasphemy, and because You, being a man, are making Yourself God” (vv. 31-33). The Jews understood very well that Jesus’ words meant that He claimed to be God. After hearing these words they wanted to stone Him to death. A claim was made by Jesus, and an accusation was charged by the Jews, both of which concerned His divinity. Was Jesus insane? Did He speak pure nonsense just to cause people to kill Him? Or was He a swindler setting up some kind of a scheme? If so, what was He trying to gain? Was He trying to gain death?

    Perhaps we will go back a little bit to the earlier parts in the Gospel of John and see what it says there. John 1:18 says, “No one has ever seen God; the only begotten Son, who is in the bosom of the Father, He has declared Him.” Why has no one seen God? It is because God is invisible. Jesus said that He was the only Begotten of the Father; He expressed the invisible Father. When you see the only Begotten, you see the Father.
    Again He spoke concerning Himself, “And no one has ascended into heaven, but He who descended out of heaven, the Son of Man, who is in heaven” (3:13). Have you ever heard anyone say such words? I cannot say, “No one has been to Shanghai, but he who comes from Shanghai to Tientsin, even I, Watchman Nee, who is in Shanghai.” If I say so, I would be gibbering nonsense. But Jesus was speaking a heavenly language. He said that He came out of heaven and is still in heaven. What can a person be if he can be in two places simultaneously? Either he is God or he is a lunatic or he is a liar. If you have not yet believed in Christ, please give a verdict to this issue. Who is this man?
    Let us read John 3:31-32: “He who comes from above is above all; he who is from the earth is of the earth and speaks out of the earth. He who comes from heaven is above all. What He has seen and heard, of this He testifies, and no one receives His testimony.” He said that He came out of heaven and was above all. After a while He said the same thing again. Let us see what is the purpose behind these words. He came to preach the things of heaven, but no one received His words. He mentioned words like “heaven,” “above all,” “out of heaven,” etc. What kind of man was He? Confucius never said this. Neither did Sakya Muni or Mohammed. Was Jesus of Nazareth a madman, a liar, or the Son of God?
    John 5:17 says, “But Jesus answered them, My Father is working until now, and I also am working.” He always put Himself in the same place as the Father. Verse 18 says, “Because of this therefore the Jews sought all the more to kill Him, because He not only broke the Sabbath but also called God His own Father, making Himself equal with God.” When we read His words now, we may consider them to be ordinary remarks. But the Jews knew what He was saying. They knew that He was making Himself equal with God. The words in fact meant that God is His Father and He came to express God. The invisible One is God, and the visible One is He. Therefore, the Jews sought to kill Him. What should we do about such an unusual person?

    John 6:46 says, “Not that anyone has seen the Father, except Him who is from God, He has seen the Father.” Here the word is clearer. He said that no one other than Himself has ever seen God. Only He knew what the Father is like. I can only say with soberness and reverence that Jesus of Nazareth is the Son of God. Read John 8:18. What did He say? “I am One who testifies concerning Myself, and the Father who sent Me testifies concerning Me.” The question in verse 19 is most interesting: “They said then to Him, Where is Your Father? Jesus answered, You know neither Me nor My Father; if you knew Me, you would know My Father also.” Have you seen what He was saying? They had seen Him, yet did not know Him. Of course they would not know the Father either, whom they had not seen. If men knew Him, they knew God. Who is He then? If knowing Him equals knowing God, is that not the same as saying that He is God and God is He?
    Read John 8:23: “And He said to them, You are from below, I am from above; you are of this world, I am not of this world.” The preposition “from” in this verse is ek in Greek. It means “out of.” That is how it should be translated. He said, “You are out of this world, but I am not out of this world.” This man claimed to be from above; He did not come out of this world. Who can He be?
    The Jews were confused. They were totally bewildered. Who was this man? The ancestor of the Jews is Abraham. They boasted of being the descendants of Abraham in the same way the Chinese boast of being the offspring of Hwang-ti. The name Abraham was highly venerated among the Jews. Now they brought out Abraham. Please read John 8:53: “Are You greater than our father Abraham, who died? The prophets died too. Who are You making Yourself?” How did Jesus answer them? Was He greater or smaller than Abraham? In verse 56 Jesus said, “Your father Abraham exulted that he would see My day, and he saw it and rejoiced.” What is this? Even Abraham had to look forward to Jesus! Hence, verse 57: “The Jews then said to Him, You are not yet fifty years old, and have You seen Abraham?” Now please pay your attention to Jesus’ answer in verse 58: “Truly, truly, I say to you, Before Abraham came into being, I am.” Tell me who this man is. If I told you that before Hwang-ti was, I, Watchman Nee am there, you would immediately write me off as a lunatic. Some of you would say that I am a liar. The words Jesus spoke made Him either a madman, a liar, or God. There can be no fourth alternative.

    We have to read on. In John 10:37-38 Jesus said, “If I do not do the works of My Father, do not believe Me; but if I do them, even if you do not believe Me, believe the works so that you may come to know and continue to know…” Know what? The clause following is very crucial. It is a big statement: “…that the Father is in Me and I am in the Father.” Who then is this man? He said that He was in God and God was in Him.
    Passages like the above are numerous in the Bible. I shall mention one more. Read carefully John 14:6-7: “Jesus said to him, I am the way and the reality and the life; no one comes to the Father except through Me. If you had known Me, you would have known My Father also; and henceforth you know Him and have seen Him.” It says clearly that if you know Jesus of Nazareth, you have known the invisible God. Why is this so? It is because He is God.

    One of the disciples was confused. John 14:8 says, “Philip said to Him, Lord, show us the Father and it is sufficient for us.” Philip was asking to be shown the Father who had been mentioned again and again by Jesus. Verse 9 says, “Jesus said to him, Have I been so long a time with you, and you have not known Me, Philip? He who has seen Me has seen the Father; how is it that you say, Show us the Father?” Here Jesus made it very plain that to see Him is to see God. He made no apology about it. He is God. There is no need to see the Father anymore. If you see Him, you see God!
    Who is Jesus of Nazareth? What would you say? Is He merely the founder of the Christian religion? Is He merely an example of self-sacrifice and humanitarianism? Is He a social reformer? Is He an advocate for universal love, peace, and freedom? Listen to what He said about Himself. He said that He is God. What is your conclusion? Is He a lunatic or a liar? Is He a hoax, or is He God? This is a vital question.
    Can He be a madman? If you read His biographies in the Gospels and observe His life and manner, you will realize that not only was He sane and sound, He was very sober and firm. If there is a perfectly sound person in this world, He has to be the One. His mind was clear, and His mentality was alert. If you study His deeds and words carefully, you have to confess that His thoughts are very logical and consistent, and His manners are most comely and appropriate. To opposing ones He only needed to reply a few sentences, and their arguments against Him were defeated. He did not have a trace of madness in Him. A madman could never have done what He did.
    Then is He a liar? A liar always lies for a profit. If there is no profit to be gained, what is the purpose of lying? Why was Jesus crucified? For no other reason than that He claimed to be God. At the last judgment, the hour when His release or crucifixion was to be deliberated, He was examined as to who He was. What was His answer? He said that the Son of Man would be seen sitting on the right hand of the Majesty on high, descending on the clouds in glory (Matt. 26:64). Even then He claimed to be God. As a result, He was crucified on the cross. Is there a liar who would sacrifice his life for his lie?

    Once I met a person who wanted to talk with me about our faith. He read some books about Jesus and admitted that Jesus had a high standard of morality. He could consider Jesus as a perfect man, a model for humanity. But he could not believe that Jesus is God. I said, “If you admit that He has a high standard of morality, then He at least is not a liar. If you agree that He is not a liar, then you have to accept His claim of divinity as truth. He repeatedly asserted that He is God. If you admire His morality, you have to recognize His divinity as well. Jesus of Nazareth is God!”

    Please read John 1:1: “In the beginning was the Word, and the Word was with God, and the Word was God.” Verse 14 says, “And the Word became flesh and tabernacled among us (and we beheld His glory, glory as of the only Begotten from the Father), full of grace and reality.” What is the “Word” mentioned in verses 1 and 14? Verse 1 speaks of the relationship the Word has with God. In reference to when, the Word was there from the beginni
