“A child kicks his legs rhythmically through excess, not absence, of life. 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’ … 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 he 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. The repetition in Nature may not be a mere recurrence; it may be a theatrical encore.”
G. K. Chesterton, Orthodoxy, p. 41
One of the results of sin is that everything gets boring. We get tired of everything in life. But God never gets bored by life, he is life. What this means is that there’s no reason to worry that we’ll get bored in eternity. Not because we’ll be tricked or have our wills removed but because we’ll be more alive than ever before.
