Yet perhaps even this view falls short of the truth. It is not simply that God has arbitrarily made us such that He is our only good. Rather, God is the only good of all creatures: and by necessity each must find its good in that kind and degree of the fruition of God which is proper to its nature. The kind and degree may vary with the creature's nature: but that there ever could be any other good is an atheistic dream. ... George Macdonald... represents God as saying to men, 'You must be strong with my strength and blessed with my blessedness for I have no other to give you.' That is the whole conclusion of the matter. God gives what He has, not what He has not: He gives the happiness that there is, not the happiness that is not. To be God - to be like God and to share His goodness in creaturely response - to be miserable - these are the only three alternatives. If we will not learn to eat the only food that the universe grows - the only food that any possible universe can ever grow - then we must starve eternally.
