If I had my two year old son's energy and youthful sense of wonder, I could probably run a marathon every day. I would never get tired, and it would never get old. The way he runs back and forth across the same path on the floor over and over and over; the way he can keep singing the same song without it ever getting old; the way he can keep asking for the same book every night; and his ability to continue to be entertained by the same episode of the same children's show over and over again--it reminds me of something G.K. Chesterton said.
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.
-G.K. Chesterton, Orthodoxy
I don't know the details of how God creates and sustains creation, but I believe we do see a faint glimpse of his infinite power when we see the vitality of children. Even more astonishing is that we human beings have the least wisdom when our energy is at its peak. Yet God not only has infinite power, but infinite wisdom to go along with it.
Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearchable. He gives power to the faint, and to him who has no might he increases strength. Even youths shall faint and be weary,
and young men shall fall exhausted; but they who wait for the Lord shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.
-Isaiah 40:28-31
Awesome.
