C.S. Lewis on WorshipReflections on the Psalms (Harvest Books, 1964), p. 177.
When I first began to draw near to belief in God and for some time after it had been given to me, I found a stumbling block in the demand so clamorously made by all religious people that we should “praise” God; still more in the suggestion that God himself demanded it. We all despise the man who demands continued assurance of his own virtue, intelligence or delightfulness; we despise still more the man who crowd of people round ever dictator, every millionaire, every celebrity, who gratify that demand. Thus a picture, at once ludicrous and horrible, both of God and of His worshippers, threatened to appear in my mind. It was hideously like saying, “What I most want is to be told that I am good and great”. Worst of all was the suggestion of the very silliest Pagan bargaining, that of the savage who makes offerings to his idol when the fishing is good and beats it when he has caught nothing. More than once the psalmists seemed to be saying, “You like praise. Do this for me, and you shall have some.”
