I pray. I mean, at one time I thought I didn't. But at my age I now admit that I have said a lot of things that were, in fact, prayers. For example, when I sign my name on a raffle ticket, I do pray that my number would be picked
So, to answer KrispyKreme's question, I would imagine myself praying that I've picked the right number in the unlikely event that I decide to buy a lotto ticket. Why not?
But as KennyV has seemed to point out, God is not an oracle. He has better things to do than being one.
