How do we know Jesus is our Substitute according to the Bible?

Jesus' role as our Substitute is echoed throughout Scripture, particularly in Matthew 27 where He accepts the punishment deserved by others, notably Barabbas. This illustrates the prophetic fulfillment found in Isaiah 53, which speaks of the suffering servant who bears our sins. Additionally, the New Testament reinforces this concept, with Paul stating in 2 Corinthians 5:21, 'For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.' This substitution is a testament to God's perfect plan for redemption, demonstrating His commitment to justice while providing a means of salvation for His chosen people.
