What does the Bible say about God forgiving sin?

The Scriptures proclaim that God is unique in His ability to forgive sin, as seen in Micah 7:18-20 where He pardons iniquity and passes by the transgressions of His remnant. This forgiveness does not rest on human effort or merit but is entirely based on God's sovereign grace. For instance, Revelation 13:8 refers to Christ as the Lamb slain from the foundation of the world, signifying that forgiveness was secured through Christ's sacrifice before we even existed. True salvation begins with the realization that we do nothing to earn God's forgiveness; it is given according to His will and purpose, as expressed in 2 Timothy 1:9. Thus, God's act of forgiveness is a profound declaration of His mercy, revealing the heart of the Gospel.
