Romans 3:19-22
Now we [all] know that everything the law says applies to those who are under [obligation to obey] that law, [Note: Here "the law" appears to refer to the Old Testament Scriptures generally, since Psalms and Isaiah are quoted. See verses 10-18]. This is so that the mouth of every objector may be stopped [i.e., from making excuses for his sin], and thereby bring the entire world under God's judgment [i.e., both Jews and Gentiles].
Romans 8:1
Therefore, none of those who are in [fellowship with] Christ Jesus will be condemned.
Romans 8:33-34
Who will bring an accusation against God's chosen people? [Certainly not God, for] He makes people right with Himself.
