OK heres a scenario for you:
Bob lives on an Island called Boogalooga with his tribe in the middle of the Pacific. He has lived there all his life. They have never had contact with Christians, and the Boogaloogan's worship several deities, including a fish god, rain god, and earth god.
Bob leads a good life, worships his gods, including making fish god idols etc.
Bob dies.
What happens when Bob fronts up at the Pearly gates?
