There are folks who just fundamentally refuse and won’t. God knows who they are. What we see is like, at best, a time slice of a soul. God sees the whole eternity’s worth of the soul. Anyhow because we can’t see what God can, we can’t conclude any specific person is utterly lost short of his or her death.
Anyhow those folks will ultimately get their wish. They will be rapt in the devil and his incredible hate of God, and get what the devil gets, and not want to leave their environs no matter how horrible it gets.
God says that there are people living who are beyond salvation, who “cannot repent.” Again, I will not claim to know who these people are. But scripture gives us good clues.
They will be instrumental in the Great Tribulation, of their own wills.
