📖 Biblical Definition
The clean heart is the heart God Himself creates — washed by sacrificial blood, indwelt by His Spirit, single in devotion. David prays it after his great sin: "Create in me a clean heart, O God; and renew a right spirit within me" (Psalm 51:10). The Hebrew verb baraʾ ("create") is the same verb used of Genesis 1 creation — only God can do this. It is both gift and goal: the regenerate condition that marks every true saint (Acts 15:9) and the daily prayer that sanctifies him until he sees God (Matthew 5:8: "Blessed are the pure in heart: for they shall see God"). Christian men pray for clean hearts daily, knowing only the Creator can produce them.

Moralism imagines the clean heart as the result of trying harder. Therapeutic culture redefines purity as feeling good about oneself. Both treat cleanness as something we manufacture and maintain.
David did not say “wash my heart”—he said create. Clean hearts are made out of nothing by the same God who said “Let there be light.” The blood of Christ purges; the Spirit indwells; faith unfeigned binds the gift to the giver.
