Martin Luther, in his famous work, Table Talk, shares this conversation he had with a friend:

“I cannot think what we shall find to do in heaven,” mused Luther. “No change, no work, no eating, no drinking, nothing to do.”

“Yes,’ replied his friend, “Lord, show us the Father, and that it sufficeth us.”

“Why of course,” responded Luther. “That sight will give us quite enough to do!”
