Yes, all people are saved by faith.
God is just. While He doesn’t tell us how exactly He is going to deal with those who have NEVER heard the gospel and have had no verbal witness to the work of Christ on the cross, He no doubt has a plan for dealing with that.
Romans 2:12-16
12For all who have sinned without the law will also perish without the law, and all who have sinned under the law will be judged by the law. 13For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified. 14For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. 15They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them 16 on that day when, according to my gospel, God judges the secrets of men by Christ Jesus
So, whats the final take? Are the tribals saved without faith?
But God's justice also includes punishment.
He no doubt has a plan for dealing with that
No doubt? You are 100% sure?
Romans 2:12-16
Ah, I see, because Paul says so? That makes all the difference...I guess.
