The author wrote this book with the feeling that many people he pastored could quote the words "The Lord is my Shepherd, I shall not want," when in reality their lives were "wildernesses of want." In this day of turmoil, confusion, and urgency, the Christian needs to know the Lord as his Shepherd. Centering on the imagery of the shepherd's care for his sheep, Ketcham draws the themes of rest, refreshment, guidance, courage, restoration, comfort, supply, protection, mercy, and power into practical focus. Courage: "The sheep needs courage, not to fight the lion, but to trust the shepherd." Supply: "It is not so much a lot of 'things' which the dear Saviour provides for us, as it is Himself."
