Psalm 37:1 Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity.
2 For they shall soon be cut down like the grass, and wither as the green herb.
3 Trust in the Lord, and do good; so shalt thou dwell in the land, and verily thou shalt be fed.
4 Delight thyself also in the Lord: and he shall give thee the desires of thine heart.
5 Commit thy way unto the Lord; trust also in him; and he shall bring it to pass.
"Fret not!? That's just plain hill-billy! Stop fretting about that aching head and sour look!"
Open up a comfortable KJV reading of Psalm 37 and notice what the healing song comes from the page. Yes, it is longer than Psalm 91, much shorter than television or games. I suggest that Psalm 37 will always lift one up, listen to God's advice, and stop fretting!
When looking for Psalm advice, look for new ones and pursue the Psalm favorites of all time. They are like Handel's Messiah because Handel has hymnified the Scriptures.
