What does the Bible teach about forgiveness of sins?

According to Scripture, forgiveness is intricately linked to redemption through Christ's sacrifice. Ephesians 1:7 states that we have forgiveness of sins through the blood of Christ, demonstrating that without His atoning sacrifice, forgiveness would be impossible. The concept of forgiveness is grounded in God's grace, which is extended to those who believe. Importantly, no human effort or sacrificial work can achieve forgiveness, as seen in Psalm 49:7, which declares that no man can redeem his brother. Instead, forgiveness signifies a restoration of relationship with God, secured through the grace-filled act of Christ on the cross.
