What does the Bible say about the sinfulness of man?

The Scriptures clearly articulate the extensive nature of human sinfulness, asserting that 'There is none good, no, not one' (Romans 3:10). According to Jeremiah 17:9, the heart is deceitful above all things, indicating that every aspect of our being is tainted by sin. Furthermore, the biblical portrayal of man's righteousness is bleak, stating that even at his best state, he is vanity. This grim reality underscores the necessity of recognizing our need for redemption through Christ, as only He can transform our filthy rags into garments of righteousness through His sacrificial work.
