If God isn't moved by direct prayers–oh Lord, please help me!–perhaps He will be moved by trash talking (via Washington Monthly):

Unhelpful for establishing the tone McCain sought in Davenport was the Rev. Arnold Conrad, past pastor of the Grace Evangelical Free Church. His prayer before McCain arrived at the convention center blocks from the Mississippi River appeared to dismiss faiths other than Christianity and cast the election as a referendum on God himself.

"I would also pray, Lord, that your reputation is involved in all that happens between now and November, because there are millions of people around this world praying to their god — whether it's Hindu, Buddha, Allah — that his opponent wins, for a variety of reasons," Conrad said.

"And Lord, I pray that you would guard your own reputation, because they're going to think that their god is bigger than you, if that happens. So I pray that you will step forward and honor your own name with all that happens between now and Election Day," he said.

To me this sounds a little bit like a threat. Good thing the Reverend Wright didn't say it, otherwise we'd never hear the end of it.

UPDATE: I changed the title of the post.  And pmayo has suggested that this argument functions somewhat like an ad populum: remind the Lord of Hosts that the consequences of his inaction during the current election may include his being the subject of interreligious trash talking.  

In other matters, congratulations to Paul Krugman, winner of the 2008 Nobel Prize economics.
