Keep in mind that if it is all just a wager, the odds don't look very good. Those who choose to deny religion, along with those who sit on the fence, and also those who choose the wrong god(s), have to hope that the actual god is one who is forgiving of such choices (in which case, why even put humanity through all of this?). If it is one of the many gods who are not forgiving --say, the kind who threaten eternal suffering for anyone who did not meet 100% of the requirements-- then we're all doomed to an eternity of suffering at the hands of a very cruel being.
With so many religions and religious denominations --many which demand exclusive and rigid devotion-- the odds are that most people will fall short. On the other hand, the idea of a god who wants everyone to be saved, but allows such splintering of support over time, doesn't make sense. Such a god really can't exist.
