I'll leave it to the masterfully simple-yet-eloquent C.S. Lewis . . .
"… 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 . We are far too easily pleased."
"I believe in Christianity as I believe that the sun has risen: not only because I see it, but because by it I see everything else."
