There is a famous story about the grandson of a Hasidic rebbe, who was playing hide-and-seek.
When it was the boy’s turn to hide and his friends could not find him, they left.
Realizing that no one was looking for him, the child ran to his grandfather and burst into tears.
“Grandfather! I hid, but no one is looking for me!”
When his grandfather heard this, he was very moved; and he replied, “This is exactly what God is saying: I hid, but no one is looking for Me.”
That is the wonder within the concealment of God: it is a concealment so dense that we forget that Someone is hiding there.
—Rabbi Adin Steinsaltz
