Not sure about that. I suspect there are millions, if not billions, in Africa, the Middle East and China who have yet to hear and have a real chance to accept the gospel. I don’t think it is enough to know Christianity exists. I think they need a real chance to learn about it from authorized teachers and to accept it by baptism.
Yes, but many countries Islamic especially, will have people im-prisoned or killed for learning about Christianity let-alone converting....
I would assume GOD has a plan for people that are not allowed to hear the Gospel because of evil regimes....
