a righteousness that is by faith
Romans 1:17 For in the gospel a righteousness from God is revealed, a righteousness that is by faith from first to last, just as it is written: "The righteous will live by faith."
Romans 3:22 This righteousness from God comes through faith in Jesus Christ to all who believe.
Romans 4:5 However, to the man who does not work but trusts God who justifies the wicked, his faith is credited as righteousness.
Romans 4:13 It was not through law that Abraham and his offspring received the promise that he would be heir of the world, but through the righteousness that comes by faith.
Romans 10:6-10 But the righteousness that is by faith says: "Do not say in your heart, 'Who will ascend into heaven?'" (that is, to bring Christ down) "or 'Who will descend into the deep?'" (that is, to bring Christ up from the dead). But what does it say? "The word is near you; it is in your mouth and in your heart," that is, the word of faith we are proclaiming: That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.
Galatians 2:15-16 "We who are Jews by birth and not 'Gentile sinners' know that a man is not justified by observing the law, but by faith in Jesus Christ. So, we too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by observing the law, because by observing the law no one will be justified."
