Article 1 of 4 | When You Live Like a Fool
By Dr. Timothy Mann
When the Bible calls someone a fool, it isn't commenting on intelligence. Psalm 53 says the fool is the person who looks at everything God has placed in creation and conscience and still declares in his heart, "There is no God." That verdict, God's own appraisal, applies to anyone who lives as though He does not exist, whatever letters follow their name.
The Fool God Is Talking About
David doesn't waste words getting to his point. Psalm 53 opens with a verdict, not a debate:
"The fool has said in his heart, 'There is no God.' They are corrupt, and have done abominable iniquity; there is none who does good" (Psalm 53:1).
Notice where the denial happens. Not in a lecture hall. Not in a courtroom. In the heart. This is a settled conviction someone has decided to live by, whatever they might say out loud at a dinner party.
Hebrew has three different words for fool, and David reaches for the strongest one available: nabal. This isn't the person who makes an occasional poor decision. This is someone who has descended, deliberately, into the deepest kind of depravity because he has rejected the one truth that holds everything else together.
I've pastored for over thirty years, and here's what surprised me early on: most of the fools I've met are brilliant. Nabal-style folly has nothing to do with a low IQ.
Intelligence Has Nothing to Do With It
Scripture never says the fool lacks education. Some fools hold doctorates. Some write bestselling books, run successful companies, and raise decent families. Others can't hold a job and end up in prison. God doesn't sort fools by intelligence, morality, or social standing. He sorts them by a single question: do you acknowledge Me?
That's an uncomfortable claim in a culture that equates intelligence with wisdom, but the Bible has never made that trade.
"Professing themselves to be wise, they became fools" (Romans 1:22).
You can be brilliant and still be a fool. Paul suggests the two often travel together, because rejecting God requires a willful blindness that has nothing to do with IQ.
You Already Know
Here is what makes the fool's denial so serious: it isn't ignorance. Paul tells us God has placed three unmistakable truths within every person: His existence, His judgment, and His moral law written on the conscience (Romans 1:19-22, 32; 2:14-15). Nature itself testifies. Every sunrise, every newborn child, every law that holds the universe together is God declaring His own existence to a world that keeps covering its ears.
So the fool doesn't lack evidence. He suppresses it.
"When they knew God, they glorified Him not as God, neither were thankful" (Romans 1:21).
The real diagnosis isn't ignorance. It's rebellion dressed up as unbelief.
Think about what that means practically. The fool isn't someone who has honestly examined the evidence and concluded, reluctantly, that God doesn't exist. Scripture says he already knew. He looked at the created order, felt the weight of his own conscience accusing him, and decided, in his heart, to override both. That's a far more serious offense than honest confusion. It's willful suppression of what he could plainly see.
What This Looks Like Up Close
Scripture gives us a living picture of this in a man whose actual name meant fool: Nabal, in 1 Samuel 25. He was crude, harsh, ungrateful, and utterly unapproachable. The Bible calls him a son of Belial, a worthless man. Nabal is what Psalm 53:1 looks like with skin on: corrupt, doing abominable deeds, failing to do good.
And that second failure matters as much as the first. The fool isn't only doing wrong; he's neglecting right.
"Therefore, to him who knows to do good and does not do it, to him it is sin" (James 4:17).
We are just as accountable to God for the good we withhold as for the evil we commit.
Nabal's story ends the way it began, badly. Scripture tells us the Lord struck him after a night of drunken revelry, and he lingered ten days in a coma before he died (1 Samuel 25:36-38). That's not a footnote. It's a warning. God's judgment falls on every fool who denies and defies Him, whether the sentence comes suddenly or slowly. None of us should carry on as though a day of reckoning isn't coming for everything we've ever said or done (Ecclesiastes 11:9-12:14).
Application & Reflection
The Bible's diagnosis isn't reserved for the atheist down the street. It's aimed at anyone who lives, practically, as though God isn't watching, and that includes plenty of us who would never say the words out loud. Ask yourself honestly this week: are there rooms in your life where you act as though God isn't in them? Decisions you make, words you speak, thoughts you entertain, as though Psalm 53's verdict doesn't touch you too?
The remedy isn't sharper arguments or more education. It's repentance, turning from the heart that says "no God" toward the God who has never stopped revealing Himself. If these questions are stirring something in you, bring them to a local church that still takes God's Word at its word. That's exactly where they belong.
In the next article, we'll see that Psalm 53 doesn't stop with the atheist. David turns the mirror on the whole human race, including you and me.
Frequently Asked Questions
What does the Bible mean by calling someone a fool?
In Psalm 53:1, the biblical fool (Hebrew: nabal) is someone who has deliberately rejected God's existence and lives as though He doesn't exist, despite the evidence God has placed in creation and conscience. It describes a moral and spiritual condition, not a lack of intelligence.
Does the Bible say atheists are unintelligent?
No. Scripture never links foolishness to low intelligence. Romans 1:22 says people "professing themselves to be wise" become fools precisely because they suppress what they know about God, regardless of education or achievement.
How does God reveal Himself to people who have never heard the gospel?
Romans 1:19-20 teaches that God reveals His existence and eternal power through creation itself, and Romans 2:14-15 teaches that His moral law is written on every human conscience. No one has a valid excuse for unbelief.
Who was Nabal in the Bible?
Nabal was a wealthy but wicked man in 1 Samuel 25 whose name literally means "fool." His harsh, selfish, ungrateful character illustrates in real life what Psalm 53:1 describes in principle.
