We must make clear that by the works of the law, the world will not be justified, but will be held accountable:
I. Accountable for being under sin’s dominion. (9-10a)
II. Accountable for practice of sin in thoughts/words/action (10b-18).
III. Accountable in knowing silence (19-20).
So what????

9 What then? Are we Jews any better off? No, not at all. For we have already charged that all, both Jews and Greeks, are under sin, 10 as it is written: “None is righteous, no, not one; 11 no one understands; no one seeks for God. 12 All have turned aside; together they have become worthless; no one does good,not even one.” 13 “Their throat is an open grave; they use their tongues to deceive.” “The venom of asps is under their lips.” 14 “Their mouth is full of curses and bitterness.” 15 “Their feet are swift to shed blood; 16in their paths are ruin and misery, 17 and the way of peace they have not known.” 18 “There is no fear of God before their eyes.” 19 Now we know that whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God. 20For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin.
