What the Bible says about God's Indictment of All Mankind
(From Forerunner Commentary)
This passage is a major indictment of mankind. Notice the terms he uses—“none” and “all,” that is, none is good, all are evil. David, the author of Psalm 14 from which Paul drew Romans 3:10-18, believed this truth a thousand years before the apostle, and in Psalm 14, David attributes this declaration to God Himself.
