For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.
2 Corinthians 5:21
And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness.
But of Him you are in Christ Jesus, who became for us wisdom from God—and righteousness and sanctification and redemption
1 Corinthians 1:30
But now the righteousness of God apart from the law is revealed, being witnessed by the Law and the Prophets, even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference
Now to him who works, the wages are not counted as grace but as debt. David, But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness
For if by the one man’s offense death reigned through the one, much more those who receive abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.)
