Mud pies

In "The Weight of Glory," C.S. Lewis says:

Indeed, 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 half-hearted 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 mud pies in a slum because he cannot imagine what is meant by the offer of a holiday by the sea. We are far too easily pleased.

 Charles Spurgeon ought to stir us up even further when he says:

O true believer, called by grace and washed in the precious blood of Jesus, thou hast tasted better drink than the river of this world's pleasure can give thee; thou hast had fellowship with Christ; thou hast obtained the joy of seeing Jesus, and leaning thine head upon His bosom. Do the trifles, the songs, the honors, the merriment of this earth content thee after that? If thou art wandering after the waters of Egypt, oh, return quickly to the one living fountain; the waters of Sihor may be sweet to the Egyptians, but they will prove only bitterness to thee. What hast thou to do with them? Jesus asks this question - what wilt thou answer him?
