27 Then what becomes of boasting? It is excluded. By what law? By that of works? No, but by the law of faith.
28 For we hold that a person is justified by faith apart from works prescribed by 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 God is one; and he will justify the circumcised on the ground of faith and the uncircumcised through that same faith.
Paul ends chapter 3 with a defense of justification by faith alone. Paul probably more than likely anticipated the negative reaction his message would have with many in his audience, but especially the Jew. Because the Jews had been conditioned to believe that redemption depended on some inherent qualification or status among those who were saved. The same problem still exists today. People still approach this topic with assumptions about what’s required to enter heaven, whether it’s certain works or qualifications.
So Paul launches a preemptive strike here with – where there us boasting? Paul ask is there any room in God’s plan for mans pride or boasting of self? He didn’t say it’s not necessary – it was clearly shut out by God. Paul ask what kind of law can declare men righteous but do so in such a way that it excludes boasting by men? It must be a law or principle other than a law of works – it’s a law of faith. God has established a law that leads men into righteousness, and this law is a law with only one requirement – faith in Christ. And remember that faith is a gift, leaving men nothing to boast about. Now talking to the Jewish foundation and leadership of this church, Paul clearly says that we maintain theat men are justified apart from the works of the Law and only by faith. For God is working in all mankind through the same means.
31 Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
A powerful verse. Did God’s use of a law of faith, nullify – abolished Old Testament bring to an end – the Mosaic Law? No, not at all, on the contrary, we establish it. The Law is to be understood as a picture of God’s righteousness, mainly His plan to redeem men. So as men obey the law of faith and are justified, the Law’s purpose is being met in that moment. Secondly, the Law stands as a model of righteousness lived out. So when we are saved by faith, the law’s two purposes are established; salvation by atonement is accomplished, and righteous living becomes possible. The great connecting tread of the Old Testament vs. New Testament in that the Old Testament demands a solution to sin that only the New Testament can fulfill.
