Before he was king, David was a shepherd. As he spent his days and nights looking after sheep in the desert, he learned some of life's most important lessons. This great future leader learned that he was, before anything else, a sheep of God's pasture, under the shepherd's care. Years later, after manying victories & many defeats, he put these life lessons into words. Psalm 23 is David's manifesto. His creed. His statement of faith and purpose. It's a summary of life's most important lessons.
