Can We Know What We Can’t Show?

We can almost hear the protests of those who claim that no one can know God or who support a story about a big bang or the many stories of evolutionism. They may accuse us of not understanding science. They may say that science is the one area that’s exempt from showing or proving its points. However, they have lost the distinction between observation and stories about the past. They rely on a wide variety of fallacies to make their case, but underlying all these fallacies is a firm commitment to a belief that the human mind can generate truth without the benefit of either observation or divine revelation. Beyond that, they believe that their particular self-generated “truth” is true while anything that conflicts with their belief is false.

The well-known atheist, Aron Ra,  said, “If you can’t show it, then you don’t know it.”

In this, he committed many fallacies. Most obviously, if that statement were true, it proves too much. In other words, it proves things that Aron didn’t intend to prove. Show me molecules turning into people over millions of years. Show me a big bang in which nothing or some unknown something turns into the universe we now see. Let me watch that happen. If you can’t show it, then you don’t know it.

We could rationally say, “If you don’t have a way that we can all repeatedly test it and observe it, then you don’t know it scientifically. And if God hasn’t revealed it in a way that we can all receive that same revelation (e.g., Him speaking through the Bible), then you don’t know it spiritually.” That might be closer to a rational statement. Someone may be able to improve on that, but it seems pretty close to right.

Aron’s statement is also an argument from ignorance fallacy. It says, “Whatever you can’t show me, you don’t know.” However, we all know things that we can’t show anyone else. Do you have pain? If you can’t prove that to me, then you don’t have pain. Have you lost your sense of taste? Unless you can show it, you still have your sense of taste. You’re ability to show me something has no impact on what you know. You should be able to explain how you know what you know. For instance, you might say, “I know I have pain because I can feel it.” I can say that I’m sorry to hear about it, but I can’t really feel your pain.

We find that skeptics are selective in their skepticism. They tend to be skeptical about God, creation, and the Genesis Flood but certain of things like evolutionism, big bang theory, abiogenesis, relativism, and post-modernism.

Aron implies that he doesn’t know that God exists. But he can’t show it. So, according to his own logic, Aron does know that God exists unless he can prove that to me. Well, at least he can’t know that he doesn’t know of the existence of God. God says he knows. If he can’t prove to me that he doesn’t know, then he doesn’t know that he doesn’t know. To be consistent, he would have to say, “I can’t show my lack of knowledge of God, so I might know that God exists.” He claims to be certain that he doesn’t know God exists, but he can have no such certainty. He might know but be hiding it from his consciousness. Well, that’s pretty close to what God says. He says that every person knows and that some people suppress this truth in their unrighteousness.

Not only that, Aron’s statement is a mind-reading fallacy. Aron is telling us what we know or don’t know. He’s claiming to know all about the spiritual experience of every person who has ever lived. Unless we can show Him that we know Jesus Christ and have that personal relationship with Christ, we aren’t having that relationship with Christ. That’s his claim and a common claim of those who resist Christ.

So how are these two situations different. On the one side, God is saying that He knows what’s in the mind of every person. God is saying that all atheists know that God exists and that God has revealed a lot about Himself to them. On the other side, Aron is saying that he knows what’s in the mind of every Christian. Aron is saying that no Christian knows that God exists and that no Christian knows anything about God. How are those two claims different?

One is a claim that God makes. The other is a claim that a human being makes. Of course, Aron presupposes no all-powerful, all-knowing God, so he would say that a non-existent God cannot possibly reveal anything. However, that’s a claim he bases on made-up stuff. And yet, he would say that his made-up stuff is real since he’s convinced of it. And the argument can go on forever.

The only way to know that any interpretation of any observation is true is by divine revelation. Jesus Christ is real. He’s not a theory or a pipe dream. He hasn’t wandered off somewhere. As Paul stated, He’s not far from any one of us. He’s very close to Aron. He’s at hand. He leads, teaches, and corrects each of us who follows Him. We’re learning to discern His voice from all others and to respond in submission.

Not only so, but Aron doesn’t have to accept anyone’s word for this. Aron can test this. Anyone can test this. Whoever seeks Christ finds Christ. Whoever is on the side of truth finds Christ. Whoever sincerely wants to know about reality finds Christ. Christ knows the innermost mind of every person. He knows who is sincere and who is insincere.



If you desire the truth, The Reason Collection is for you. At the intersection of faith and reason is a place called sanity. As we focus on this intersection, we realize that we can’t separate reason and rational thought from faith.

The Reason Collection will . . .

  • Demolish the lies of ungodly thinkers.
  • Show how rational thought is impossible without faith.
  • Explain how we can know without question that the Bible is true and without error.
  • Reveal how we can know that no personal revelation will ever conflict with the Bible even though divine revelation may correct our interpretations of the Bible.
  • Dissolve doubts and establish the truth on the only firm Foundation, Jesus Christ.
  • Answer the questions and objections of those who are hostile to Christ.
  • Teach how to discern between truth and error.
  • Understand how to sort through the many voices claiming authority.

This collection is a deep dive rather than a superficial explanation. It doesn’t create a stalemate where neither ungodly thinkers nor Christians can prove their points. Rather, it explains how to prove the truth of Christ and the Bible with absolute certainty, and it leaves the ungodly thinker with bare claims and fallacies.

The Reason Collection will consist of six books because of the technical limitations of print-on-demand. It started as four books, but one became two and then three.


Three books focus on our rational thought journey as followers of Christ. One book focuses on the logic of the Nye-Ham Debate. Two books are reference texts you’ll want to keep on hand. We’re currently rendering these books into ebooks. Petros has no definite plan for a date to publish the print versions. Petros has graciously given Real Reality permission to distribute the ebooks free. An audiobook will follow if God’s grace allows. We’ll allow a little time for advance reading copies before the ebooks will be available free to the general public.
