I think hell has its place. My question is whether or not it is remedial. I'm completely disengaged from the idea of divine punishment, and human for that matter. Moreover, if hell is remedial then the implication is that it need not be eternal.
I think there's a reason we see early Greek speaking Christians understanding hell to be remedial- Origen, Gregory of Nyssa, and his wise, older sister Macrina. I think they read various passages as speaking to an "age" and not an "eternity." That's a well-worn argument.
A punishing fire is unbecoming of a good God. Purifying fire seems highly likely, on the other hand.
It's no mystery. If anyone wants to know how a story ends, they peek at the last pages of the book. The Bible's no different. John's final vision in Revelation undeniably supports the idea that the Lake of Fire is remedial - and fulfils prophecy as per the final chapters of Isaiah.
Follow the vicissitudes of the nations.
They went up on the breadth of the earth and surrounded the camp of the saints and the beloved city. And fire came down from God out of heaven and devoured them. (Rev 20:9)
Looks like curtains for the enemies of God...but wait:
He who sits on the throne said, “Behold, I am making all things new.” (21:5) Next, heaven is descends to earth in the form of the New Jerusalem. (21:10), and we're told...
The nations will walk by its light, and the kings of the earth and the nations will bring their glory and honour into it; (21:24,26)
So the nations are delivered from the consuming fire repentant. They are also purified, so they can enter the City of God, since we're advised of the conditions of entry:
nothing unclean, and no one who practices abomination and lying, shall ever come into it, but only those whose names are written in the Lamb’s book of life. (21:27)
But there's more. Once they proceed through the ever-open gates (21:25), they find:
a river of the water of life, clear as crystal, coming from the throne of God and of the Lamb, in the middle of its street. On either side of the river was the tree of life, bearing twelve kinds of fruit, yielding its fruit every month; and the leaves of the tree were for the healing of the nations. (22:1-2)
Wow! Did you get that? The nations are consumed by holy fire, and then admitted to heaven purified to worship the Almighty and to be treated with the healing leaves from the tree of life. There will no longer be any curse (22:3).
But it's no cakewalk. They need encouragement to overcome:
The Spirit and the bride say, “Come.” And let the one who hears say, “Come.” And let the one who is thirsty come; let the one who wishes take the water of life without cost. (22:17)
So our job is to encourage the cowardly and unbelieving and abominable and murderers and immoral persons and sorcerers and idolaters and all liars (21:7) to no longer do wrong or remain filthy (22:11), but 'wash their robes, so that they may have the right to the tree of life, and may enter by the gates into the city.' (22:14), and so ultimately: The grace of the Lord Jesus be with all. Amen. (22:21)
So let's start by encouraging each other! Cast out that unbelief in God's perfect plan to be all in all.
