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 for infancy; for we have sinned and grown old, and our Father is younger than we. The repetition in Nature may not be a mere recurrence; it may be a theatrical encore.
—G.K. Chesterton, Orthodoxy (1908)
Jesus called a small child over to him and put the child among them. Then he said, "I assure you, unless you turn from your sins and become as little children, you will never get into the Kingdom of Heaven. Therefore, anyone who becomes as humble as this little child is the greatest in the Kingdom of Heaven. And anyone who welcomes a little child like this on my behalf is welcoming me. But if anyone causes one of these little ones who trusts in me to lose faith, it would be better for that person to be thrown into the sea with a large millstone tied around the neck.—Matthew 18:2-6
