A blunt truth Scripture never softens—and mercy never ignores.
Learn to hate sin like God does, and learn to love righteousness too. Learn how to wisely show love to stupid people like He did and does. Toward all people. Pray for stupid people, all people and don't let yourself fall into any sin patterns and be stupid. All sin is destructive and stupid. Pray for those once lived as drunks, but now sober.. people who still act horribly towards others.
The God of Scripture is kind, but He and it is never naïve. Grace is gentle, but truth is sharp like a sword. And one truth the Bible teaches plainly—though we often resist it—is this: sin does not merely make us guilty; it makes us foolish. Or, as I bluntly puts it, “Sin literally makes you stupid.”
That is not crude exaggeration; it is biblical diagnosis. It is what it is.
The Bible repeatedly links sin with darkened understanding, clouded judgment, and spiritual dullness.
“The god of this world has blinded the minds of unbelievers” (2 Corinthians 4:4). “They became futile in their thinking, and their foolish hearts were darkened” (Romans 1:21). Sin doesn’t announce itself as insanity or stupidity—it disguises itself as a good reason.
How sin distorts the mind unto stupidity
Sin rarely arrives screaming. It whispers. It convinces otherwise rational people to do unthinkable things—and then explains them away afterward. Greg Laurie describes sin’s effect with painful accuracy:
It clouds judgment. People under sin’s influence make decisions they once swore they never would—compromising convictions, staying in dangerous patterns, excusing what once repulsed them. “There is a way that seems right to a man, but its end is the way to death” (Proverbs 14:12).
It blinds perception. Sin narrows vision. Immediate relief feels wiser than long-term obedience. Eternal consequences fade beneath temporary comfort. “They have eyes to see but do not see” (Jeremiah 5:21).
It causes spiritual amnesia. God’s past faithfulness is forgotten. Lessons learned are unlearned. Miracles fade faster than cravings. Israel sang on one shore and complained on the next. “They soon forgot His works” (Psalm 106:13).
It destroys perspective. Sin pulls the camera lens inward. Self eclipses God. Comfort outweighs calling. Eternity shrinks to the size of a moment. “Set your minds on things above, not on earthly things” (Colossians 3:2).
It deceives the intelligent. Sin does not target the ignorant alone. Brilliant minds commit absurd acts when conscience is silenced. Education does not protect the heart. “The heart is deceitful above all things” (Jeremiah 17:9).
John MacArthur once warned, “Sin promises freedom but delivers slavery—and the chains are often invisible at first.” Chuck Smith echoed the same truth: “The enemy always shows you the pleasure and hides the price.”
Biblical case studies in spiritual foolishness
Scripture does not sanitize its own heroes, but stays honest—and that shows mercy.
Peter lingered where he never belonged. He had multiple chances to leave the courtyard, yet stayed—warming himself by enemy fires—until courage collapsed and denial followed. Sin often begins with simply staying too long (Luke 22:54–62).
Samson assumed yesterday’s anointing would cover today’s rebellion. He toyed with sin until the Spirit withdrew—and he didn’t even notice. “He did not know that the Lord had left him” (Judges 16:20). That sentence should sober every believer.
David chose cover-up over confession. One sin demanded another. Lies stacked upon lies until death entered the story. “When I kept silent, my bones wasted away” (Psalm 32:3).
Jonah wept over a plant and resented a revival. He valued personal comfort over the salvation of thousands. Sin can shrink compassion until mercy feels offensive (Jonah 4).
Billy Graham once observed, “Sin will take you farther than you ever intended to go, keep you longer than you ever intended to stay, and cost you more than you ever intended to pay.” That is not poetry—it is prophecy.
Need to hear a modern voice on this truth?
George Barna's research consistently shows that many professing Christians think no differently than the surrounding culture -- on moral issues—not because they lack intelligence, but because unchecked sin dulls real discernment. Spiritual compromise for believers wrecks their testimony. When truth is wrongly negotiated by believers, wisdom erodes.
Even our hymns warned us from long ago:
“Prone to wander, Lord, I feel it—
Prone to leave the God I love.”
— Come Thou Fount
Or as another song confesses:
“Amazing grace, how sweet the sound,
That saved a wretch like me—
I once was lost, but now am found,
Was blind, but now I see.”
Grace restores sight. Sin can remove it. Remember blind Sampson.
A wiser way forward
The goal is not merely to avoid consequences, but to recover clarity. Scripture calls us to sobriety of mind, alertness of soul, and ruthless honesty with sin. “Awake, O sleeper, and arise from the dead, and Christ will shine on you” (Ephesians 5:14).
Hate sin—not because it is unfashionable, but because it lies. Reject foolishness—not because it embarrasses us, but because it enslaves. Love God—not sentimentally, but obediently.
John Piper writes, “Sin is what you do when your heart is not satisfied with God.” And that dissatisfaction always clouds judgment.
The invitation of Scripture is not merely to be forgiven—but to be made wise. “The fear of the Lord is the beginning of wisdom” (Proverbs 9:10). Wisdom begins where sin ends and truth is obeyed.
And clarity returns when repentance becomes immediate, obedience becomes joyful, and Christ becomes supreme once again.
