"Good people have no reason to envy the worldly prosperity of wicked people, nor to grieve or be uneasy about it. Because the prosperity of the wicked will soon be at an end." (Matthew Henry) "It is foolish to fret and rage and storm against the ungodly whom we see prospering, since they will certainly be cut off sooner or later - sooner rather than later." (Pulpit Commentary) In Psalm 37:1-3, 7&9, David issues a warning that every saint of God needs to heed in this hour. He also offers four (4) directives that will cause every believer to be victorious in such troublesome times.
