It is simply impossible for God to lack any good thing, because by his very life and being he is the one who has everything that truly and really is good. So God is God, fully and completely, apart from us and apart from the world he has made.
When the apostle Paul was asked to tell some people about who God really is, he talked about this very thing. In Acts 17:24-25 Paul said, “The God who made the world and everything in it, being Lord of heaven and earth, does not live in temples made by man, nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything.” The reason that God cannot be given anything is clear–God already has it all! For this very reason, God is the one who gives to all of creation what it needs, while nothing in all of creation can give to God anything that he supposedly lacks…
…We should be humble before this great and mighty God, realizing that while we can give nothing to him that he doesn’t already have, HE has everything that we need. Our hearts should long to praise this God and to live in dependence upon him. Yes, indeed, God deserves nothing less.
