But Israel, who followed after the law of righteousness, has not attained to the law of righteousness.
Read Chapter 9
Faith is the fulfilling of the law. It is because the Gentiles have faith that they appear to fulfill the whole law. But the Jews, who out of envy did not believe in the Savior, because they claimed the righteousness which is commanded in the law, i.e., the sabbath, circumcision, etc., did not come to the law. In other words, they did not fulfill the law, and those who do not fulfill the law are guilty of it. Commentary on Paul’s Epistles.
