What does 2 Corinthians 5:21 teach us about Jesus?

In 2 Corinthians 5:21, Paul articulates one of the most profound truths of the gospel: '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 verse encapsulates the essence of substitutionary atonement, where Christ, although sinless, took on the sins of His people. This act was done so that believers might be declared righteous and accepted by God. It illustrates God's profound love and the sacrificial nature of Christ's mission. The imputation of sin to Christ and the imputation of righteousness to believers highlight the grace of God that transforms lives and assures salvation.
