You mean the sinful men and women in the Amazon that suppress the truth in unrighteousness...to whom all that can be known of God is plain...who knew Him but did not honor Him nor were thankful? Those for whom there is no excuse? (Rom 1)
I think Scripture is pretty clear exactly what will happen to them.
You were saying to TaraP — “You mean the sinful men and women in the Amazon that suppress the truth in unrighteousness...to whom all that can be known of God is plain...who knew Him but did not honor Him nor were thankful? Those for whom there is no excuse? (Rom 1)”
It’s true that all have the general revelation of God, which will lead them to pray to this Creator God, asking for further revelation in what they should do (which would be in terms of salvation). Anyone who calls on God, from general revelation (that we all have, no matter where we are) — God will provide the specific revelation for salvation.
Whether this be by missionary, specifically sent by God, or an angel sent for this specific purpose — one way or another God will answer the prayers of them who are honestly seeking him, having seen His general revelation in Creation and knowing that He is our Creator God. God will not disappoint this person, no matter where they are on this earth, and no matter what time period it is in or was in — when they “call upon God” having seen Him in His Creation (as God intended it to be...)
Lastly, you said — “I think Scripture is pretty clear exactly what will happen to them.”
Yes, those who respond to God’s revelation in Creation, knowing that there is a Creator God out there, and wanting to know the plan of salvation — will be given that revelation for purposes of salvation. Those who refuse the revelation of God, seeing in creation, the works of this Creator God, will be as Romans 1 says, and as Revelation 20 says (in the Great White Throne judgement).
Also, remember that the Gospel of Jesus Christ, of His salvation will be given to the whole world, by means of an angel, at a particular time in Revelation.
6 Then I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth—to every nation, tribe, tongue, and people—
7 saying with a loud voice, “Fear God and give glory to Him, for the hour of His judgment has come; and worship Him who made heaven and earth, the sea and springs of water.”
*This* is the time that the gospel is given to the whole world, and “then” the end comes...
