It is not a necessary either-or in God’s view. There is a curious statement in the gospels that Sodom will rise up and condemn Bethsaida and Corazin at the judgment “BECAUSE THEY WOULD HAVE REPENTED.” Perhaps this means elect, although (as all men) sinners, who had not heard the gospel yet and thus not been able to accept.
And to move it to modern days, churches full of self and devoid of gospel keep on aggravating the situation.
The people’s of Judea had the laws of God, they were accountable to them, and yes l, Sodom would rise to scream condemnation because it would not seem fair that a city of believers would go uncondemned while they were condemned.
