"God moves in extremely mysterious, not to say circuitous, ways. God does not play dice with the universe; He plays an ineffable game of His own devising, which might be compared, from the perspective of any of the other players*, to being involved in an obscure and complex version of poker in a pitch-dark room, with blank cards, for infinite stakes, with a Dealer who won't tell you the rules and who smiles all the time."
*ie., everybody
Terry Pratchett and Neil Gaiman, Good Omens
