What does the Bible say about substitution in Christ?

Substitution is a foundational truth in the Bible, especially illustrated in 2 Corinthians 5:21, where we see that Christ was made sin for us so that we could be made the righteousness of God. Throughout Scriptures, the concept of substitution is emphasized. For example, in Isaiah 53, we learn that Christ bore our griefs and sorrows, and the iniquity of us all was laid upon Him. Understanding this doctrine is crucial, as it encapsulates the redemptive work of Christ and reveals the core message of the gospel, which is central to the Christian faith.
