My logic is that there is only upside to being an atheist or agnostic. Generally I don't believe in afterlife. So say I die, and then there is Christ in afterlife. Won't he be forgiving enough to forgive me my mistake of not believing? I'm sure he'll be generous. From not expecting anything to going to heaven. Nice!
