the eternal boredom of heaven?

“And I made him a man of the world. If it had not been for me, he would still be a needless gardener- pretending to cultivate a weedless garden that grew right because it couldn’t grow wrong- in ‘those endless summers the blessed ones see.’ Think of it, ye Powers and Dominions! Perfect flowers! Perfect fruits! Never an autumn chill! Never a yellow leaf! Golden leopards, noble lions, carnivores unfulfilled, purring for his caresses amidst the aimless frisking of lambs that would never grow old! Good lord! How bored he would have been! How bored! Instead of which, did I not launch him on the most marvelous adventures? It was I who gave him history. Up to the very limit of his possibilities. Up to the very limit… And did not you, O Lord, by sending your angels with their flaming swords, approve of what I had done?”

~ Satan to God in a conversation from H.G. Wells Undying Fire, a modern re-writing of the story of Job

"The humans live in time, and experience reality successively. To experience much of it, therefore, they must experience many different things; in other words, they must experience change. And since they need change, the Enemy (being a hedonist at heart) has made change pleasurable to them, just as He has made eating pleasurable. But since He does not wish them to make change, any more than eating, an end in itself. HE has balanced the love of change in them by a love of permanence. He has contrived to gratify both tastes together in the very world He has made, by that union of change and permanence which we call Rhythm. He gives them the seasons, each season different yet every year the same, so that spring is always felt as a novelty yet always as the recurrence of an immemorial theme."
