Would it be reasonable for every human on Earth to prepare themselves for eventual death by not accepting one religion but by accepting them all? I don't want to start another theist-atheist debate but this would also include preparing for oblivion without a god. A working knowledge of all religions would amount to a further stretching of Occam's Razor, improving one's afterlife chances even more wouldn't you think? Why stop at one belief when you can cover them all. So why don't we do it?
