In Psalm 23, we find David's perspective as a shepherd himself of God as our Shepherd. The Good Shepherd leads His sheep to the provision of daily food in green pastures, and for quietness of mind, He finds still waters to bring us to. When the pests of life threaten to overwhelm us and make life crazy, He anoints our heads with the oil of His goodness and mercy. You can follow Him, even through the darkest dark, in that valley of the shadow of death.
