In our new series on Psalm 23, we study the first verse, in which David establishes the awesome concept that the Lord is our Shepherd. But that also means that we are sheep, who are known to be dependent, somewhat unintelligent, stubborn, hesitant to listen and prone to wander away. So we need a Shepherd, and because the Lord is so gracious and faithful, we can confidently rely on Him for all we need. He claims us as His own, and then turns our negative attributes into powerfully positive ones.
