What does the Bible say about forgiveness through Christ's blood?

Ephesians 1:7 declares, 'In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace.' This indicates that forgiveness is not only a gift but is intimately tied to the sacrificial death of Jesus Christ. His blood shed on the cross represents the ultimate price paid for our sins. No other sacrifice, such as those described in the Old Testament, could take away sin; only the blood of the Son of God is sufficient for our redemption.
