It is the argument that believing in God is the most logical thing to do since if there is a God and you deny Him, then you are in trouble. If there is no god and you accept Him, there is no problem because it doesn't matter. Logically, it is better to not deny that God exists than to deny He does. There is truth to this argument, but the problem is that it does not define which "god" to believe in since in many religions, believing in a different god brings a punishing judgment. Nevertheless, this does not excuse a person from at least trying to discover if there is a God or not and who he might be.
