How do we know Christ was made sin?

The notion that Christ was made sin is emphasized in 2 Corinthians 5:21, which states, 'He hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.' This indicates that Christ did not merely bear our sins but was made sin itself, taking on the full weight of sin's penalty. It is crucial to recognize that this act was necessary for our redemption, as He bore our sins in His own body on the tree (1 Peter 2:24). Hence, the reality of Christ being made sin is foundational to understanding the atonement.
