Pastor, here’s how to answer “If God is real, then prove it.”

You’ve heard it in a hospital hallway, in a counseling appointment, maybe in your own head at 2 a.m.: “If God were real, my mom wouldn’t have died.” “If God existed, He’d make it more plain.” It sounds like an honest question. It isn’t. It’s the oldest sermon of the serpent, and the first one he preached to Jesus. Here’s how to hear what’s underneath it, and how I answer it as a pastor.

What conditionalism is

As I use the word here, conditionalism means making belief in God depend on God passing my test. The person appoints themselves the examiner, writes the exam, and names the passing score. “If You’re real, You’ll do this.” And when God doesn’t perform on cue, the verdict comes back: He must not exist, or He must not be good.

Notice who’s sitting in the judge’s chair. That’s the whole problem.

The serpent’s question

In the wilderness, Satan comes to a hungry Jesus and says, “If you are the Son of God, tell these stones to become bread” (Matthew 4:3). Keep the grammar: if you are, then do this. It’s an attack on identity, not appetite. And it’s the same question every conditionalist asks: “Did God really reveal Himself, or would He have shown up when I asked?”

Jesus refuses the frame. He doesn’t perform a miracle to settle the argument. He answers from what is written: “Man shall not live on bread alone, but on every word that comes from the mouth of God” (Matthew 4:4).

Step 1 — Name the false premise

Suffering is normal. Grief is real, and pastors should never rush past it. The error isn’t the pain. It’s the false premise and the false conclusion: “God didn’t heal me, so He isn’t real.” Gently ask the question underneath: who appointed us the examiner? If God’s existence depends on my perspective, I’ve forced God to submit to me instead of me submitting to Him.

Step 2 — Point to what God has already said

God doesn’t need to meet our standard for revelation, because He has already revealed Himself. In creation: “The heavens declare the glory of God” (Psalm 19:1), so clearly that people are “without excuse” (Romans 1:20). And fully, in His Son: “In the beginning was the Word” (John 1:1). I actually think science is one of the great places to become a believer. The deeper you go into the complexity of the universe, the louder it points to a powerful Creator.

Step 3 — Flip the suffering argument

People use suffering as proof God isn’t there. But His comfort in suffering is proof that He is. We couldn’t get through suffering without Christ. Job never got his answer. He got God Himself, and it was enough. Faith that’s conditional on outcomes is weak. Faith rooted in what is true holds.

Step 4 — Call it what it is, kindly

Especially in Western Christianity, we can make our stomach our god: if God doesn’t meet this need, He must not be God. Paul said it plainly about people whose “god is their belly” (Philippians 3:19). When God has to function the way I demand, I’ve made myself sovereign, and that’s idolatry. Say it with tears if you need to. But say it, because idolatry leads to death, and His word is better than life.

He is, He was, and He always will be. That doesn’t depend on our test. The right response isn’t to demand proof. It’s to stand in awe and worship God for how big He has revealed Himself.
