What does the Bible say about Jesus being the Lamb of God?

The Bible consistently portrays Jesus as the Lamb of God, notably in passages like Matthew 26, where His trial symbolizes the ultimate sacrifice for sin. Jesus' role as the Lamb fulfills prophecies that date back to the Old Testament, illustrating God's sovereign plan for redemption. The imagery of the Lamb is deeply rooted in the sacrificial system, where the innocent suffered for the guilty. This notion is epitomized in Isaiah 53:7, which states, 'He was oppressed and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter.' Thus, Christ, in His innocence, accepted the burden of sin to ensure the salvation of His people.
