Let God Be True
Paul sharply rebukes the Jews, who teach the Gentiles from a faith that has dwindled to outward form. They answer that their disobedience actually displays God’s righteousness. Why, then, should they be reproached for it?
Being the chosen people who had received the law only made them proud. It never grew into true faith. No matter how a son sins, his father’s goodness is not erased. In the same way, human falsehood and unfaithfulness cannot shake the truthfulness of God in the least. Human sin cannot bring God’s plan to a halt.
Though Israel rejected the gospel, God did not cast them off altogether. He raised up Paul, himself a Jew, to bring it to the Gentiles. Jew and Gentile alike, all are under sin, and repentance comes not through excuses but only by looking to the cross.
