God's Peace!
Your deepest most constant need should be for God's Peace. God has planted Peace in the garden of your heart, but there are weeds growing there too; pride, worry, selfishness, and unbelief. However, God is the Gardener, and He is working to rid your heart from those weeds. God does His work in various ways. When you sit quietly with Him, He shines the light of his presence directly into your heart with a heavenly light and Peace grows abundantly, and weeds shrivel up. He also sends trials into your life. When you trust God in the midst of trouble, Peace fourishes and weeds die. Thank God for troublesome situations; the Peace they can produce far outweighs the trials you endure.
