Jesus is our righteousness because His perfect life and sacrifice are imputed to us by grace through faith.
The Bible clearly teaches that the righteousness necessary for salvation cannot be earned through our deeds but is a gift from God. In Psalm 71:16 and through the scriptures, we understand that Christ’s righteousness is counted to those who believe in Him, fulfilling the requirements of God's law perfectly. Paul emphasizes this in 2 Corinthians 5:21 where he states that God made Christ, who knew no sin, to be sin for us so that we might become the righteousness of God in Him. Thus, our justification before God is solely based on Christ’s completed work, not our own merit.
