Evidence for God's Existence

Sue Bohlin


Romans 1 says that God has planted evidence of Himself throughout His creation so we are without excuse. In this essay weíll be looking at different types of evidence indicating that God really does exist.

A "Just Right" Universe

There's so much about the universe, and our world in particular, that we take for granted because it works so well. But Christian astronomer Dr. Hugh Ross has cited twenty-six different characteristics about the universe that enable it to sustain life. And there are thirty-three characteristics about our galaxy, our solar system, and the planet Earth that are finely-tuned to allow life to exist.{1} I do well to make the meat, potatoes, vegetables, and bread all come out at the same time for dinner; we're talking about fifty-nine different aspects all being kept in perfect balance so the universe hangs together and we can live in it!

Our Earth, for instance, is perfectly designed for life. It's the "just right" size for the atmosphere we need. Its size and corresponding gravity hold a thin, but not too thin, layer of gases to protect us and allow us to breathe. When astronaut John Glenn returned to space, one of the things that struck him was how thin and fragile our atmosphere is (only 50 miles above the Earth). If our planet were smaller it couldn't support an atmosphere, like on Mercury. If it were larger, like Jupiter, the atmosphere would contain free hydrogen, which is poison for us.{2} Earth is the only planet we know of that contains an atmosphere that can support human, animal, and plant life.

The Earth is also placed at a "just right" distance from the sun and the other planets in our solar system. If we were closer to the sun, we'd burn up. If we were farther away, we'd freeze. Because Earth's orbit is nearly circular, this slightly elliptical shape means that we enjoy a quite narrow range of temperatures, which is important to life. The speed of Earth's rotation on its axis, completing one turn every 24 hours, means that the sun warms the planet evenly. Compare our world to the moon, where there are incredible temperature variations because it lacks sufficient atmosphere or water to retain or deflect the sun's energy.

Speaking of the moon, itís important that there is only one moon, not two or three or none, and it's the "just right" size and distance from us. The moon's gravity impacts the movement of ocean currents, keeping the water from becoming stagnant.{3}

Water itself is an important part of a "just right" world. Plants, animals and human beings are mostly made of water, and we need it to live. One of the things that makes Earth unique is the abundance of water in a liquid state.

Water has surface tension. This means that water can move upward, against gravity, to bring liquid nutrients to the tops of the tallest plants.

Everything else in the world freezes from the bottom up, but water freezes from the top down. Everything else contracts when it freezes, but water expands. This means that in winter, ponds and rivers and lakes can freeze at the surface, but allow fish and other marine creatures to live down below.

The fact that we live on a "just right" planet in a "just right" universe is evidence that it all was created by a loving God.

The Nagging Itch of "Ought"

As a mother, I was convinced of the existence of a moral God when my children, without being taught, would complain that something wasn't "fair." Fair? Who taught them about fair? Why is it that no one ever has to teach children about fairness, but all parents hear the universal wail of "That's not fa-a-a-a-a-air!" The concept of fairness is about an internal awareness that there's a certain way that things ought to be. It's not limited to three-year-olds who are unhappy that their older siblings get to stay up later. We see the same thing on "Save the Whales" bumper stickers. Why should we save the whales? Because we ought to take care of the world. Why should we take care of the world? Because we just should, that's why. It's the right thing to do. There's that sense of "ought" again.

Certain values can be found in all human cultures, a belief that we act certain ways because they're the right thing to do. Murdering one's own people is wrong, for example. Lying and cheating is wrong. So is stealing. Where did this universal sense of right and wrong come from? If we just evolved from the apes, and there is nothing except space, time, and matter, then from where did this moral sense of right and wrong arise?

A moral sense of right and wrong isn't connected to our muscles or bones or blood. Some scientists argue that it comes from our genes -- that belief in morality selects us for survival and reproduction. But if pressed, those same scientists would assure you that ultimate right and wrong don't exist in a measurable way, and it's only the illusion of morality that helps us survive. But if one researcher stole another's data and published results under his own name, all the theories about morality as illusion would go right out the window. I don't know of any scientist who wouldn't cry, "That's not fair!" Living in the real world is a true antidote for sophisticated arguments against right and wrong.

Apologist Greg Koukl points out that guilt is another indicator of ultimate right and wrong. "It's tied into our understanding of things that are right and things that are wrong. We feel guilty when we think we've violated a moral rule, an "ought." And that feeling hurts. It doesn't hurt our body; it hurts our souls. An ethical violation is not a physical thing, like a punch in the nose, producing physical pain. It's a soulish injury producing a soulish pain. That's why I call it ethical pain. That's what guilt is -- ethical pain."{4}

The reason all human beings start out with an awareness of right and wrong, the reason we all yearn for justice and fairness, is that we are made in the image of God, who is just and right. The reason we feel violated when someone does us wrong is that a moral law has been broken -- and you can't have a moral law without a moral law giver. Every time we feel that old feeling of, "It's not fa-a-a-a-a-air!" rising up within us, it's a signpost pointing us to the existence of God. He has left signposts pointing to Himself all over creation. That's why we are without excuse.

Evidence of Design Implies a Designer

If you've ever visited or seen pictures of Mount Rushmore, you cannot help but look at the gigantic sculpture of four presidents' faces and wonder at the skill of the sculptor. You know, without having to be told, that the natural forces of wind and rain did not erode the rock into those shapes. It took the skilled hands of an artist.

William Paley made a compelling argument years ago that the intricacies of a watch are so clearly engineered that it cannot be the product of nature: a watch demands a watchmaker. In the same way, the more we discover about our world and ourselves, the more we see that like an expertly-fashioned watch, our world and we ourselves have been finely crafted with intentional design. And design implies a designer.

Since we live in our bodies and take so much of our abilities for granted, it's understandable that we might miss the evidence of design within ourselves -- much like a fish might be oblivious to what it means to be wet. Dr. Phillip Bishop at the University of Alabama, challenges us to consider what would happen if we commissioned a team of mechanical engineers to develop a robot that could lift 500 pounds. And let's say we also commissioned them to design a robot that could play Chopin. They could probably do that. But what if we asked them to come up with a robot that could do both, and limit the robot's weight to 250 pounds, and require that it be able to do a variety of similar tasks? They'd laugh in our faces, no matter how much time or money we gave them to do it. But you know, all we'd be asking them to do is to come up with a very crude replication of former football player Mike Reid.{5}

Probably the greatest evidence of design in creation is DNA, the material of which our genes are made, as well as the genetic material for every living thing on the planet. One of the startling discoveries about DNA is that it is a highly complex informational code, so complex that scientists struggle hard to decipher even the tiniest portions of the various genes in every organism. DNA conveys intelligent information; in fact, molecular biologists use language terms -- code, translation, transcription -- to describe what it does and how it acts. Communication engineers and information scientists tell us that you can't have a code without a code-maker, so it would seem that DNA is probably the strongest indicator in our world that there is an intelligent Designer behind its existence.

Dr. Richard Dawkins, a professor of biology who writes books and articles praising evolution, said in his book The Blind Watchmaker, "Biology is the study of complicated things that give the appearance of having been designed for a purpose."{6} Even those who desperately fear the implications of design keep running into it.

Those who deny the evidence of a designer are a lot like the foolish fisherman. If he fails to catch a fish, he says, "Aha! This proves there are no fish!" He doesn't want to consider the possibility that it might be he is an inept fisherman. Since science cannot measure the intangible or the supernatural, there are many people who say, "Aha! There is no Creator."{7} Foolish fishermen deny the evidence that God exists and has left His fingerprints all over creation.

The Reliability of the Bible

Every religion has its own holy book, but the Bible is different from all the others. It claims to be the very Word of God, not dropped out of the sky but God-breathed, infused with God's power as He communicated His thoughts and intent through human writers.

The Bible was written over a period of 1500 years, by about forty different writers, on three different continents. They addressed a wide variety of subjects, and yet the individual books of the Bible show a remarkable consistency within themselves. There is a great deal of diversity within the Bible, at the same time displaying an amazing unity. It presents an internally consistent message with one great theme: God's love for man and the great lengths to which He went to demonstrate that love.

If you pick up any city newspaper, you won't find the kind of agreement and harmony in it that is the hallmark of the biblical books. A collection of documents that spans so much time and distance could not be marked by this unity unless it was superintended by one Author who was behind it all. The unity of the Bible is evidence of God's existence.

One other aspect of the Bible is probably the greatest evidence that God exists and that He has spoken to us in His holy book: fulfilled prophecy. The Bible contains hundreds of details of history which were written in advance before any of them came to pass. Only a sovereign God, who knows the future and can make it happen, can write prophecy that is accurately and always -- eventually -- fulfilled.

For example, God spoke through the prophet Ezekiel against the bustling seaport and trade center of Tyre. In Ezekiel 26:3-6, He said He would bring nations against her: "They shall destroy the walls of Tyre and break down her towers; and I will scrape her soil from her, and make her a bare rock." Ezekiel 26-28 has many details of this prophecy against Tyre, which would be like Billy Graham announcing that God was going to wipe New York off the map.

Tyre consisted of two parts, a mainland city and an island a half- mile offshore. The first attack came from the Babylonian king Nebuchadnezzar, who laid siege to Tyre for thirteen years. Finally, his battering rams broke through the walls, and he tore down the city's towers. But the island part of the city wasn't yet destroyed, because this prophecy was fulfilled in stages. For 250 years it flourished, until Alexander the Great set his sights on Tyre. Even without a navy, he was able to conquer this island city in what some consider his greatest military exploit. He turned the ruined walls and towers of Old Tyre into rubble, which he used to build a causeway from the mainland to the island. When he ran out of material, he scraped the soil from the land to finish the land- bridge, leaving only barren rocks where the old city used to be. He fulfilled the prophecy, "They will break down your walls and destroy your pleasant houses; your stones and timber and soil they will cast into the midst of the waters."{8}

Fulfilled prophecy is just one example of how God shows He is there and He is not silent. How else do we explain the existence of history written in advance?

Jesus: The Ultimate Evidence

The most astounding thing God has ever done to show His existence to us is when He passed through the veil between heaven and earth and came to live among us as a man.

Jesus Christ was far more than just a great moral teacher. He said things that would be outrageous if they weren't true, but He backed them up with even more outrageous signs to prove they were. Jesus claimed not to speak for God as a prophet, but to be God in human flesh. He said, "If you've seen Me, you've seen the Father,"{9} and, "The Father and I are one."{10} When asked if He was the Messiah, the promised Savior, He said yes.{11} He told his contemporaries, "Before Abraham was, I am."{12} The fact that His unbelieving listeners decided then to kill Him shows that they realized He was claiming to be Yahweh, God Almighty.

When Jesus told His followers that He was the Good Shepherd,{13} they would immediately be reminded of a passage in the book of Ezekiel where Yahweh God pronounced Himself shepherd over Israel.{14} Jesus equated Himself with God.

But words are cheap, so Jesus backed up His words with miracles and signs to validate His truth-claims. He healed all sorts of diseases in people: the blind, the deaf, the crippled, lepers, epileptics, and even a woman with a twelve-year hemorrhage. He took authority over the demons that terrorized and possessed people. He even raised the dead.

Jesus showed His authority over nature, as well. He calmed a terrible storm with just a word. He created food out of thin air, with bread and fish left over! He turned water into wine. He walked on water.

He showed us what God the Father is like; Jesus was God with skin on. He was loving and sensitive, at the same time strong and determined. Children and troubled people were drawn to Him like a magnet, but the arrogant and self-sufficient were threatened by Him. He drenched people with grace and mercy while never compromising His holiness and righteousness.

And after living a perfect life, He showed His love to us by dying in our place on a Roman cross, promising to come back to life. Who else but God Himself could make a promise like thatóand then fulfill it? The literal, bodily resurrection of Jesus Christ is the final, greatest proof that there is a God, that Jesus is God Himself, and that God has entered our world and showed us the way to heaven so we can be with Him forever. He said, "I am the way, the truth, and the life; no one comes to the Father except by Me."{15}

God exists, and He has spoken. He made a "just right" universe that is stamped with clues of its Maker. He placed eternity in our hearts, as Ecclesiastes tells us, and all people have a strong moral streak because we are made in the image of a moral God. The evidence of design in our bodies, our world and the universe is a signpost pointing to a loving, intelligent Designer behind it all. The unity of the Bible and the hundreds of fulfilled prophecies in it show the mind of God behind its creation. And we've looked at the way Jesus punched through the space-time continuum to show us what God looks like, and opened the doorway to heaven. Jesus is the clearest evidence of all that God does exist.
