Why do Christians need to repent?

Christians are called to repentance as a necessary response to sin, which is foundational to the Gospel. The psalmist's confession in Psalm 130 highlights recognition of iniquity and our need for mercy. Repentance is not merely feeling sorry for sin, but it is a turning away from sin and toward God. In 2 Corinthians 7:10, we see that godly sorrow produces repentance, leading to salvation. This transformative process involves a reliance on God's grace and recognition of Christ's sacrifice, bringing about restoration and renewed relationship with God.
