What does the Bible say about grace and forgiveness?

The concept of grace and forgiveness is foundational in Scripture, particularly as it pertains to the work of Jesus Christ in the redemption of His people. In 2 Kings, we see the example of Manasseh, an ungodly king who turned to God and received grace despite his depravity. This reflects the greater reality of the gospel, which teaches that through Christ's substitutionary sacrifice, believers are forgiven and cleansed from their sins. The righteousness of Jesus is imparted to those who are washed in His blood, ensuring that their iniquities are not found by God (Jeremiah 50:20). This is articulated further in 2 Corinthians 5:21, which states that God made Christ, who knew no sin, to be sin for us, that we might be made the righteousness of God in Him.
