Galatians 2:15-16

Indeed, we are Jews by birth and not “Gentile sinners,” as they are called. Yet we know that a person is put right with God only through faith in Jesus Christ, never by doing what the Law requires. We, too, have believed in Christ Jesus in order to be put right with God through our faith in Christ, and not by doing what the Law requires. For no one is put right with God by doing what the Law requires.
