If it is right for man to have the glory of God as his goal, can it be wrong for God to have the same goal? If man can have no higher purpose than God’s glory, how can God? If it is wrong for man to seek a lesser end than this, it would be wrong for God, too. The reason it cannot be right for man to live for himself, as if he were God, is because he is not God. However, it cannot be wrong for God to seek His own glory, simply because He is God. Those who insist that God should not seek His glory in all things are really asking that He cease to be God. And there is no greater blasphemy than to will God out of existence. (J.I.Packer, Hot Tub Religion)
