In our times due to the media and the high technology christian can even reach huge numbers people in Africa and other countries but what about 1000 years ago? What about those which lived in countries or continents where nobody had every come to preach about Jesus? Does this mean that millions of people went to hell without having had a chance? How do you explain this to an unbeliever? I'm afraid he'll simply say that this isn't fair and that such a God is evil.
