You asked what happens to people who live far away from the gospel and have never heard about Jesus and die without faith in him.
Here is what I think the Bible teaches.
God always punishes people because of what they know and fail to believe. In other words, no one will be condemned for not believing in Jesus who has never heard of Jesus.
Does that mean that people will be saved and go to heaven if they have never heard of Jesus? No, that is not what God tells us in the Bible.
