What does the Bible say about God's pardon for iniquity?

The Bible asserts the importance of God's ability to pardon iniquities, rooted in His justice and holiness. In Psalm 25:11, David begs for God's pardon, acknowledging the greatness of his sin. Significantly, God can forgive sin because every sin is ultimately committed against Him. The psalmist's plea highlights the need for divine intervention, as man cannot justify himself before a holy God. It underscores the theological truth found in Romans 3:19-20, which teaches that by the deeds of the law, no flesh will be justified. Forgiveness comes not by human effort but through Christ's sacrificial work, aligning with Ephesians 4:32, which emphasizes that we are forgiven for Christ's sake.
