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.
