Instead of worrying about things we can't control anyway, God has given us four pieces of wisdom in Psalm 37 that will bring peace into our lives. As we learn to "trust in the Lord, delight in the Lord, commit thy way unto the Lord and rest in the Lord", supernatural Godly peace will absolutely follow.
Psalm 37:1-3 "Quit worrying and depend on God, He'll take care of you"
Psalm 37:4 "Simply enjoy God and you'll be blessed"
Psalm 37:5-6 "Take your hands off of it; let go, let God and watch"
