One doesn't have anything to lose in believing in God. In fact, it's quite logical and reasonable to do so for a number of reasons; for example, the probability of there being a God. The majority of the world is Christian, therefore the majority of the world believe in God. When one dies they either go to Heaven, Hell, or Purgatory, according to Christianity while, on the other hand, Athiests believe they go into Mu, or nothingness. However, they cannot deny the possibility that there is a God. And even if it is the most miniscule chance, why not take it?
