Many debates about God and science orbit around “design.” People discuss whether a biological structure is too complex to arise by evolutionary processes. Those conversations can be detailed and technical. But there is another layer that often gets overlooked, a layer that is more basic than questions about biological machinery. It is the layer of information and meaning.

In the first article of our “Got Questions?” series, we asked: How can we know God exists? We considered the Bible’s claim that God has not left Himself without witness, in creation, in conscience, and supremely in Jesus Christ.

A natural follow-up often sounds like this: “I trust science. I trust airplanes. I trust the laws of nature. I do not need to add God.”

Before we go further, let me say this plainly: Christians are not anti-science. We are grateful for careful observation, honest experimentation, and true discoveries. Historically, many of the pioneers who helped build modern science were Christians, convinced that the universe is orderly and intelligible because it was made by a wise Creator. [1] The question is not whether science works. It does. The question is whether science, when you think it through, quietly points beyond itself.

1. Trusting the Airplane Assumes More than Aerodynamics

When you step onto a plane, you trust that it will fly and reach your intended destination safely. You trust the engineers, the pilot, the maintenance, and yes, the laws of aerodynamics. And you trust them because you have seen patterns. Planes have flown many times before. Experience teaches you to expect they will fly again.

That everyday confidence depends on something most of us rarely stop to examine: the reliability of human rationality. It depends on your mind being able to reason from repeated experience. It depends on the world being stable enough that patterns can be discovered and trusted.

In other words, you are not only trusting a machine. You are trusting that your mind can know real things about the world.

Now, a skeptic may say, “Evolution explains why our brains work well enough to survive.” Perhaps. But that still leaves a serious question: why should we assume our reasoning is aimed at truth, rather than merely at survival? If your deepest worldview says mind is accidental and meaning is accidental, it becomes harder to explain why the universe is intelligible, and why human minds can reliably grasp that intelligibility.

Christianity offers an answer that fits the world we actually inhabit: the universe is intelligible because it is created by a rational God, and our minds can grasp reality because we are made in His image (Genesis 1:26–27). That does not discourage investigation. It explains why investigation works.

2. Looking for God in the Machine Is the Wrong Category

Some people say, “I do not see God in the laws of aerodynamics, so God is unnecessary.”

But of course you do not “see” the maker of something as a component inside the thing. You can investigate a car for a lifetime and never find the inventor sitting under the hood. That does not mean there was no inventor. It means you are asking the wrong kind of question.

God is not a part of the universe, as though He were one more object inside the system. He is the Creator of the system. So the question is not, “Where is God inside the machinery?” The more foundational question is, “Why is there an intelligible, law-governed world at all, and why do we have minds capable of discovering it?”

And this matters: Christianity does not set God against aerodynamics, chemistry, or physics. God is not a plug-in explanation for what we cannot yet explain. He is the reason there is a rational, orderly world to investigate in the first place.
