What does the Bible say about the natural knowledge of sin?

The scripture teaches that there exists a natural knowledge of God’s law within the hearts of every person, as indicated in Romans 2:14-15. This innate understanding arises from the divine hand of God and reveals itself when individuals encounter their sinfulness and the consequent need for redemption. For example, Adam and Eve's awareness of their nakedness after the Fall illustrates how conscience points to the moral law. Their attempt to cover themselves with fig leaves reflects humanity's futile endeavor to hide from God through self-righteousness.
