How could Israel be ignorant of the righteousness of God and seek to establish their own? Because they missed Jesus Christ himself, who is the point and goal of the Law. In Romans 10:5-13, Paul shows how the Old Testament itself makes plain that right relationship to God was never about what humans do, but rather about what God has done, and that what saves any person, Jew or Gentile, is a true and living faith in Jesus Christ as the God of Israel.
