What does the Bible say about the wickedness of man?

The wickedness of man, as expressed in Psalm 36, reveals a profound spiritual corruption. The psalmist notes that the transgression of the wicked indicates a heart that is devoid of the fear of God. This absence of divine reverence leads to self-deception and allows sinful thoughts and actions to flourish (Psalm 36:1-4). Scripture teaches that without the fear of God, one cannot attain true wisdom, as stated in Proverbs, 'The fear of the Lord is the beginning of wisdom.' When left in this unredeemed state, the heart is blind to its own wickedness, ultimately leading to divine judgment (Psalm 36:12).
