Second, II Corinthians 5:21 explains how Jesus is “The Lord Our Righteousness”: “For he [i.e., God] hath made him [i.e., Christ] to be sin for us, who knew no sin; that we might be made the righteousness of God in him.”

What is meant by the Lord is our righteousness?The word Tsidkenu, the Hebrew word used for righteousness in "The Lord Our Righteousness," means upright, straight, and narrow. The righteousness of God is the root of all integrity. It is the definition of all that is genuinely good in this life.
