I don’t think there is to many more people left, who have not heard of the Gospel of Jesus Christ.....
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.
You said — “I dont think there is to many more people left, who have not heard of the Gospel of Jesus Christ.....”
Well..., that may seem to be true in the U.S. (but even here, I question that...). Aside from the U.S. there are definitely a *lot* of people who haven’t heard the Gospel of Jesus Christ.
For one example, you could start with the 1.2 billion Muslims. Perhaps take off about 10 or 20 % of them and what is left is probably those who haven’t heard of Jesus Christ as the Son of God and the Messiah of Israel and as salvation of the world.
In the Muslim world, they have heard of “a Jesus” — who is a prophet, of which Mohammed is the greatest prophet of them all...
That’s just the Muslims. There are lots of others out there who haven’t heard the Gospel of Jesus Christ.
During the Tribulation, there will be an angel who will *finally* give the Gospel of Jesus Christ to the entire world — as, what you might call, a last and final effort.
