The Lord Our Righteousness, or Yahweh Tsidkenu, is the new name announced from the heavenly throne over Christians, who are born again by faith in Christ Jesus. This declaration became active when the blood sacrifice of the Son of God was finished on the Calvary cross. The new covenant in the blood of Christ is the foundation of this justification, and whoever declares Jesus Christ as their Lord and Savior becomes ‘the righteousness of God in Him’ at that very moment. This righteousness given to humans by God is a pure gift and evidence that God is righteous in justifying sinners. This means humans are justified by RIGHT believing, not by RIGHT doing. For God made Christ, who knew no sin, to be sin (judicially) on our behalf, so that in Him we become the righteousness of God (2 Cor 5:21).
This is the good news for all mankind – the one and only declaration that makes us RIGHTEOUS and RIGHT with God!
