27 Where then is boasting? It is excluded. By what kind of law? Of works? No, but by a law of faith. 28 For we maintain that a man is justified by faith apart from works of the Law. 29 Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, 30 since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one. 31 Do we then nullify the Law through faith? May it never be! On the contrary, we establish the Law. Romans 3:27-31 (NASB)
In our last post we ended with the passage above in which Paul makes it very clear that genuine salvation is by the law of faith not by a law of works. In v28 he says, “For we maintain that a man is justified by faith apart from works of the Law.” Justification is by faith alone and does not depend at all on doing any works of the law. In vv29,30 he tells us that since God is the Lord of all, whether Jews or Gentiles, there can only be one way of justification, which is by faith alone. What does it mean that believers uphold the law rather than overthrow it by our faith? Justification by faith alone does not denigrate the law, but, instead, underscores its true importance by providing a payment for the penalty of death, which the law required for failing to keep it; by fulfilling the law’s original purpose, which is to serve as a tutor to show mankind’s utter inability to obey God’s righteous demands and to drive people to Christ (Galatians 3:24); and by giving believers the capacity to obey it (Romans 8:3,4). Then Paul moves into the obvious objection to these arguments by using the Old Testament Patriarch Abraham whom God declared righteous in Genesis 15:6.
