Self-sufficiency of God
"The Scriptures allude to the fact that God does not need anything that we humans need to survive. He requires no water, air, food, sleep or money. Counselors, supervisors, and advisors of any kind are of no need to Him. He is self sufficient in all capacities this is hard for the human brain to consider, that someone does not need what we do to survive." 
"If I were hungry I would not tell you, For the world is Mine, and all it contains. Shall I eat the flesh of bulls or drink the blood of male goats?" -Psalm 50:12-13
Thou wast, O God, and thou was blest
Before the world begun;
Of thine eternity possest
Before times glass did run.
Thou needest none thy praise to sing,
As if thy joy could fade:
Couldst thou have needed any thing,
Thou couldst have nothing made.
--John Mason, A Praise Song for Creation
