Jesus Christ Our Righteousness

Jesus Christ our righteousness offers us His righteousness by grace through faith. It's part of the classic double imputation that takes place at every conversion. Our unrighteousness is imputed to Christ, and His perfect righteousness is imputed to us: "For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God" (2 Corinthians 5:21). This is why we don't need to try to justify ourselves.
