Bargaining with God

I just saw a preview for The Adjustment Bureau (Matt Damon / Emily Blunt). I think it's supposed to be one of those predestination vs. free will kind of movies. The concept is nothing new, but almost anything with Matt Damon in it automatically becomes 100 x cooler. I'm a sucker for those butterfly effect movies.

I wonder if you can bargain with God. Probably not, but the thought is sometimes entertaining.
