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.
