I agree. Vegita, what qualifies as having the opportunity to learn about Christianity? Is it meeting a person who tries to convert you? People are trying to convert people to other religions all the time, what argument makes Christianity true and all the other ones false? Is it reading the bible? There are all sorts of religious texts, why should we believe the Bible and not any of the other ones? It seems the only answer left is that the "true" religion (christianity, in this case), must be in the natural world such that when you encounter someone converting you or the bible, you'll be able to distinguish that, yes, this is the truth. However, if evidence of Christianity is not in the natural world, than Christianity is just an arbitrary set of beliefs no different than the other thousands of religions.
