"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.
Footnote to above: * ie., everybody." -Terry Pratchett & Neil Gaiman; Good Omens
(The book is excellent, I recommend it, and both of it's authors, to anyone looking for an enjoyable read.)
