The cherished and beloved 23rd Psalm begins with both a statement and a promise. The statement: The Lord is my shepherd. And the promise: I shall not want.
It seems like the rest of the Psalm simply elaborates on this wonderful promise. For example, I will not want for:
Food – because I am made to “lie down in green pastures” (23:2)
Refreshment – because “He leads me beside the still waters” (23:2)
Forgiveness and Renewal of Spirit – because “He restores my soul” (23:3)
Direction and Guidance – because “He leads me in the paths of righteousness” (23:3)
Fear of Failure and Death – because “I will fear no evil in the valley of the shadow of death” (23:4)
His Presence, Acceptance – because “You are with me” (23:4)
Comfort and Peace – because “Your rod and Your staff they comfort me” (23:4)
Victory in the Face of Our Enemies – because “You prepare a table before me in the presence of My enemies” (23:5)
