If you believe, there should be this nagging doubt in your head. In the course of human history, there have been countless other believers in gods different from and mutually exclusive to your god. They all were sure that their god was the only or best game in town. They felt the same conviction you do. They thought their religion had the privileged place in history just like you do. They didn’t take any of the other gods that other people believe or believed in seriously—those seemed like alien and distant possibilities, just like you feel about their gods. They failed to reflect on the historical, social, and cultural role that their god played in their culture that made it so analogous to all of the other gods and other cultures. They figured that the religious worldview that they happened to be born into also just happened to be the one and only one correct one in the entire history of the human race.
So a reasonable person would have to ask herself: if my god and his relationship to me in history looks just like their god and his relationship to them, and if their god isn’t real, what exactly makes mine different? Is it reasonable to think that mine is different and that it’s only me and the tiny group of people who happen to believe just like I do that got it right?
J.L. Schellenberg, in “Pluralism and Probability,” Religious Studies, 33, 143-159. 1997, argues that the odds are always going to favor the conclusion that your view is wrong in this situation. There are just too many other gods out there that undermine the probability that you’ve got the right one.
