Forgive me, but you are ignoring obvious facts. Think about the aborigines in the Outback of Australia, those living in remote viliages in the Chinese countryside, and those who are on remote islands in the pacific who have not yet seen a white person. Think of escimos who spend their entire lives only seeing their family, or those who live in the mountains of Tibet, below the monks in the clouds. And, I can go on, and on. There will always be those who have no access to the Gospels. I mean, look at the US. My girlfriend (who is a saint, imho), was raised by two atheists who truly hated what they saw religion doing to people when they were growing up. Judge as you might, but these are two of the nicest, most giving, moral and decent people you have ever met. I guarantee it. But, the point is that my girlfriend has no real concept of God. She asks for help from me to understand the concept and, every time she asks, I find myself reaching for words. As you have probably guessed, I am facinated by this, and we talk about it all the time, but I realized a long time ago that to an objective observer (she isn't biased against religion at all and truly is fascinated to learn more about beliefs), all supernatural beliefs are just as ridiculous. Whether it's Jesus coming back from the dead, ancient alien souls, one man with direct access to God or frogs raining down from the sky, she doesn't understand the reasoning behind them. Why do people now, who have access to so much more information and understanding of the physical universe than the authors of any scripture, believe these things dogmatically, demanding no verifiable evidence. We both want to understand why.
You've got to open your mind to reality. If it is up to Christians to make salvation available to all people ... we aren't even close yet. And, making a book available is not nearly enough (and kind of pathetic, really). Imagine a child growing up in one of the communities I spoke of, and (I'll give you this one) a Christian Missionary comes to their village. Now, their parents are only used to outsiders coming close in to take advantage of them. So, understandably, they are skeptical.
Now, do you think that the child, scared and hiding, might not "take" to Christianity, even assuming that, miraculously, was translated into their native, aborigines tongue?
And, no, I don't know anyone personally who has no access to the Bible in their own native language. But, just like you, I am sheltered.
