The always brilliant C.S. Lewis includes some further thoughts on worship in The Problem of Pain:
The problem of reconciling human suffering with the existence of a God who loves, is only insoluble so long as we attach a trivial meaning to the word ‘love’, and look on things as if man were the centre of them. Man is not the centre. God does not exist for the sake of man. Man does not exist for his own sake. ‘Thou has created all things, and for thy pleasure they are and were created.’ We were made not primarily that we may love God (though we were made for that too) but that God may love us, that we may become objects in which the Divine love may rest ‘well pleased’. To ask that God’s love should be content with us as we are is to ask that God should cease to be God: because He is what He is, His love must, in the nature of things, be impeded and repelled by certain stains in our present character, and because he already loves us He must labour to make us lovable….
Clashes of interest, and therefore opportunities either of selfishness or unselfishness, occur only between beings inhabiting a common world: God can no more be in competition with a creature than Shakespeare can be in competition with Viola. When God becomes a Man and lives as a creature among His own creatures in Palestine, then indeed His life is one of supreme self-sacrifice and leads to Calvary…. [W]hen God empties Himself of His glory and submits to those conditions under which alone egoism and altruism have a clear meaning, He is seen to be wholly altruistic. But God in His transcendence–God as the unconditioned ground of all conditions–cannot easily be thought of in the same way. We call human love selfish when it satisfies its own needs at the expense of the object’s needs… [but] God has no needs…. God is goodness. He can give good, but he cannot need or get it. In that sense all His love is, as it were bottomlessly selfless by very definition; it has everything to give and nothing to receive….
Those divine demands which sound to our natural ears most like those of a despot and least like those of a lover, in fact marshal us where we should want to go if we knew what we wanted. He demands our worship, our obedience, our prostration. Do we suppose that they can do Him any good, or fear, like the chorus in Milton, that human irreverence can bring about ‘His glory’s diminution’? A man can no more diminish God’s glory by refusing to worship Him than a lunatic can put out the sun by scribbling the word ‘darkness’ on the walls of his cell. But God wills our good, and our good is to love Him (with that responsive love proper to creatures) and to love Him we must know Him: and if we know Him, we shall in fact fall on our faces…. Yet the call is not only to prostration and awe; it is to a reflection of the Divine life, a creaturely participation in the Divine attributes which is far beyond our present desires. We are bidden to ‘put on Christ’, to become like God. That is, whether we like it or not, God intends to give us what we need, not what we think we want. Once more, we are embarrassed by the intolerable compliment, by too much love, not too little. [pgs. 40-43, 46-47]
