It is one of the most common things you hear from thoughtful skeptics: "I just think it's more honest to say I don't know." The implication is that people who claim certainty about God — especially Christians — are either not thinking carefully or are letting their emotions override their reason.

It sounds humble. It sounds like the mature, measured position. And in some ways, it deserves respect. Intellectual honesty is a real virtue, and there are plenty of people who claim certainty about God without having thought very hard about it.

But the "I don't know" position is not as neutral as it sounds. And the Christian claim to know God is not the same as arrogance.

There is a difference between being humble and being uncertain. A humble person acknowledges the limits of their knowledge and remains open to correction. An uncertain person has not yet reached a conclusion.

Christians can and should be humble. We do not know everything about God. We hold some things with more confidence than others. We acknowledge that our understanding is partial and that we see, as Paul says, "through a glass darkly."

But humility does not require us to say we do not know whether God exists. A person can be genuinely humble and genuinely certain at the same time — if their certainty is based on real evidence and real experience, and if they hold it with an open hand rather than a clenched fist.

Here is something worth thinking about: saying "I don't know" is not the same as having no position. It is a position. It is the position that the evidence for God's existence is insufficient to warrant belief — or at least insufficient to warrant certainty.

That is a claim. And it is a claim that can be examined. Is the evidence for God's existence really that weak? Is the historical case for the resurrection really that uncertain? Is the fine-tuning of the universe really that easy to explain away?

The person who says "I don't know" is not standing outside the debate. They are making a judgment about the weight of the evidence. That judgment can be right or wrong — and it is worth exploring together.

Christians are sometimes accused of being closed-minded because they are certain about God. But certainty and closed-mindedness are not the same thing.

A person can be certain about something and still be willing to examine the evidence, engage objections, and update their understanding if they encounter something genuinely compelling. That is not closed-mindedness — that is intellectual integrity.

The question is not whether you are certain, but whether your certainty is warranted. And the Christian claim is that it is — not because we have stopped thinking, but because we have followed the evidence and the testimony of God's own self-revelation to a conclusion.

The Christian's certainty about God is not primarily the result of winning a philosophical argument. It is the result of encountering a person — Jesus Christ — and finding that encounter to be real, transforming, and consistent with everything else we know about the world.

This is not the same as wishful thinking. Millions of people across every culture, century, and intellectual background have come to know God personally. Their testimony is not uniform in every detail, but it is remarkably consistent in its core: God is real, he can be known, and knowing him changes everything.

The agnostic who says "I don't know" may simply not yet have encountered the full weight of that testimony — or the person of Jesus himself. That is not a reason to dismiss them. It is a reason to keep the conversation going.

When someone tells you it is more honest to say "I don't know," the best response is not to argue. It is to agree that honesty matters — and then to share honestly from your own experience. You do not know God because you worked hard enough at philosophy. You know him because he made himself known to you.

That is a testimony, not a proof. But testimonies are a form of evidence. And sometimes they open doors that arguments cannot.

The Christian Field Guide gives you practical tools for engaging the "I don't know" conversation — including how to share your own story in a way that invites rather than pushes.
