As we have already seen, one of Paul’s greatest challenges was to instruct former Jewish believers that the “baggage” they were bringing from their life-long learnings has been totally changed by the very Son of God. And today he addresses attaining righteousness – we cannot earn it; it is received only through the grace of and faith in God.
Romans 9: 30 What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; 31 but the people of Israel, who pursued the law as the way of righteousness, have not attained their goal. 32 Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the stumbling stone.
