David was very confident, not only about his present circumstances, but also that in the future God would see him all the way home. He believed that valley times were appointed for His good. He learned things about God that could be learned no other way than being in the deep ravines of life. He stayed close, trusted in God's protection and guidance all the way. All because he could say, "The Lord is my shepherd."(Like a Child, God takes care of me.)
