Everywhere in the world, parents play peek-a-boo with their children. It is a major discovery of life, a cornerstone in human development: To realize that something is there even when you cannot see it, that the world is not defined by your subjective perception, that there is something that absolutely is—whether you know of it or not.

All our life, all of the world, is G‑d playing with us that same game. He peeks with a miracle and then hides behind nature. Eventually, we look behind nature to find Him there.
