If we consider the unblushing promises of reward and the staggering nature of the rewards promised in the Gospels, it would seem that our Lord finds our desires not too strong but too weak. We are halfhearted creatures fooling about with drink and sex and ambition, when infinite joy is offered us, like an ignorant child who wants to go on making mudpies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.
C.S. Lewis, The Weight of Glory
