Why is the concept of Jesus as a sacrificial lamb important for Christians?

The concept of Jesus as the sacrificial lamb is vital for Christians as it fulfills Old Testament types and shadows of atonement, particularly seen in Leviticus 16:21 where Aaron lays the sins of the people upon the scapegoat. Jesus, being the innocent Lamb of God, embodies this sacrificial system, where His death served as the ultimate atonement for the sins of His people. By bearing our iniquities and becoming sin for us (2 Corinthians 5:21), He satisfied divine justice, allowing us to be justified and reconciled to God. This doctrine emphasizes the grace of God in salvation, as it is not through our works but through Christ's completed work that we find redemption.
