I do think that the answer to the question, what about those who've never heard the gospel, is answered in Romans 2:12-15.
Let's start with v. 15 "...which show the work of the law written in their hearts, their conscience also bearing witness...."
Even if they have never heard of Jesus, and have never heard the gospel, they have the law written in their hearts. They have a sense of right and wrong. They have a conscience. But they do not have the Law, as the Jews did.
V. 14 describes the Gentiles as a "law unto themselves."
If, then they are not condemned for reject Jesus, of whom they knew nothing, what is the basis for their condemnation? It is, I think, for a failure to keep
their own moral code. V. 15 says that conscience, or inner moral code, accuses or excuses them. They have their own moral code and still can't keep it. And neither can we who have heard the gospel.
At the judgment, they will acknowledge that they are guilty and without excuse, and that their punishment is justified.
Similarly, we are also guilty and acknowledge that we deserve eternal death. But our plea will be the blood of Jesus has covered our sin.
Earlier, one poster insisted that everybody has heard the gospel, else God wouldn't be fair. Or, they suggest that a just God won't send people who hell who've never heard the gospel.
I think my answer covers both objections. But if people will be saved without hearing the gospel, let us bring our missionaries home, please.
