How flexible are you? Paul has shown the Jews are just as inexcusable as the Gentiles are before God’s wrath. Trying to play word games will not account for righteousness before God.
Who is that masked man? The Jews had boasted in the law and thought they were exempt from God’s wrath. Paul shows the law had become a mask for them whereby they thought they were righteous.
That’s Not Fair! We all have a keen sense of not being treated fairly when someone is shown a special favor over us, though we usually don’t complain when we receive such a favor. Paul talks about God’s judgment and reveals it is both righteous and impartial.
