All-sufficiency
There is a perfection that God out of His goodness will give to man. Whatever the degree of this perfection may be, all of us will still be dependent upon an external source for our well-being. In other words man’s future perfection will never equal Gods. God’s perfection, however, excludes such a possibility of dependence, as He has no need of anything. No one can add to or subtract anything from God’s being. Neither can any one of His attributes, like His power or love, increase or decrease. God is perfect in His self-sufficiency, in His self-existence, and from all eternity. His all-sufficiency is within Himself and of Himself. This is natural for the being of God. El Shaddai is used in Gen. 17:1; the meaning is “the all-sufficient One.” Acts 17:25 states God is, “Neither worshipped with men’s hands, as though He needed anything.” Therefore there is no common ground between the perfection of God and of any creature.
Use
The perfection of God is an incommunicable attribute and is not the same as that which will be found in man. God is by nature all sufficient and who with His all-sufficiency can and will saturate the soul of man to such an overflowing measure that man will have need of nothing else but to have God as his portion. The soul so favored is filled with such light, love, and happiness, that it desires nothing else but this. “Whom have I in heaven but Thee? And there is none upon earth that I desire beside Thee” Psalm 73:25.
