How do we know that Jesus' sacrifice was enough for atonement?

The sufficiency of Jesus' sacrifice for atonement is articulated in Scripture, particularly through the lens of propitiation. In Colossians 1:20 and other passages, it is revealed that Christ bore the wrath of God for our sins, and through His blood, He reconciled us to the Father. Unlike the Old Testament sacrifices that were repeated and only temporarily covered sin, Christ's sacrifice is final and perfect, providing complete atonement and ensuring that God is no longer offended by the sins of His people.
