Galatians 2:15; Galatians 3:18; Galatians 3:21

15 "We are Jews by nature and not sinners from among the Gentiles;
18 For if the inheritance is based on law, it is no longer based on a promise; but God has granted it to Abraham by means of a promise.
21 Is the Law then contrary to the promises of God? May it never be! For if a law had been given which was able to impart life, then righteousness would indeed have been based on law.
