A classic and brilliant observation on joy from C.S. Lewis:
“We are half-hearted creatures, fooling around with drink and sex and ambition when infinite joy is offered to us, like an ignorant child who wants to go on making mud pies in the slum because he cannot imagine what is meant by the offer of a holiday at sea. We are far too easily pleased.” (The Weight of Glory)
We are so easily satiated with cheap fillers that we can hardly imagine that a far greater joy is available to us. All these substitutes point to the truer joy we are invited to enjoy in God.
