They are corrupt
14:1 They are corrupt. Psalm 53 is almost an exact replica of this psalm. Also Psalm 14:1-3 is quoted (in effect, not verbatim) in Romans 3:10-12. Evidently the Holy Spirit considers it important to emphasize that those who seek to replace the God of creation with a humanistic or pantheistic philosophy—no matter how wise they profess themselves to be—are really fools in God’s sight (note also Romans 1:21-23).
