What is the significance of Christ being made sin?

The doctrine of Christ being made sin, as articulated in 2 Corinthians 5:21, is pivotal to understanding how redemption is accomplished. 'For 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 profound exchange occurred so that the holiness of God could be upheld while allowing sinners to be declared righteous. Christ's identification with sin was necessary to fulfill the demands of divine justice, and through His sacrifice, believers are cleansed from their sin, providing them the means to be reconciled to God.
