Common misinterpretations include claiming Jesus literally became sinful in His nature rather than judicially bearing sin's penalty; assuming this guarantees universal salvation for all humanity without personal faith in Christ; suggesting believers instantly become sinless or morally perfect, overlooking the distinction between justification and progressive sanctification; or reducing the verse to Jesus merely setting a moral example instead of accomplishing penal substitutionary atonement.
II Corinthians 5:21
King James Version (1769)
21 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 passage reveals the heart of the gospel through the doctrine of imputation in Christ's atonement: God the Father made the sinless Jesus Christ to bear the full penalty of our sins as our substitute, treating Him as sinful on the cross so that believers, through union with Him by faith, receive Christ's perfect righteousness credited to their account, transforming them from enemies of God into righteous ones in His sight and enabling true reconciliation.
