I've always liked this quote from G.K. Chesterton. It's more poetic than theological, but I like how it points to God's boundless, playful creativity.
"Because children have abounding vitality, because they are in spirit fierce and free, therefore they want things repeated and unchanged. They always say, 'Do it again'; and the grown-up person does it again until he is nearly dead. For grown-up people are not strong enough to exult in monotony. But perhaps God is strong enough to exult in monotony. It is possible that God says every morning, 'Do it again' to the sun; and every evening, 'Do it again' to the moon. It may not be automatic necessity that makes all daisies alike; it may be that God makes every daisy separately, but has never got tired of making them. It may be that He has the eternal appetite of infancy; for we have sinned and grown old, and our Father is younger than we."
What do you think are some things we could all do to stay infatuated with the beauty of God's creation all around us, to maintain "the eternal appetite of infancy"?
