After this I looked, and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and before the Lamb. They were wearing white robes and were holding palm branches in their hands.
Revelation 7:9//

Note that there were people from “every” nation, tribe, people, and language. Even tribes that have never been contacted from the outside will Hage people there. Christ presents Himself to ALL people without limits. We must choose to accept Him, no matter where we are or where we came from.
