What does the Bible say about Christ as a substitute?

The doctrine of Christ as the sinner's substitute is a foundational truth of the gospel. As stated in 2 Corinthians 5:21, 'For God had made him to be sin for us who knew no sin, that we might be made the righteousness of God in him.' This teaches us that Christ took upon himself the penalty of our sin, serving as our designated representative before God. Throughout Scripture, such as in Isaiah 53, we see the prophetic declaration of Christ bearing our griefs and sorrows, emphasizing His substitutionary role. It is through His sacrifice that we are justified and made acceptable before God.

In His earthly life, Christ’s obedience to God’s law was necessary for our justification. His life exemplified perfect righteousness, and this righteousness is imputed to believers, making Christ not only our sacrifice but also our righteousness before God. Therefore, the understanding of Christ as our substitute is not just a theological concept but the very heart of the gospel that offers hope and assurance to all who trust in Him.
