I don't know whether Hell exists yet, although it certainly will (I am not a universalist). It seems to me that those headed there are awaiting the Last Judgment, after which Hell will be populated all at once. In the meantime, Hades (and the Abyss) are filling up. If indeed that is correct, and there is no current need for Hell, then it would seem inconsistent with God's amply-demonstrated creative practices for Him to create something in advance of the need for it. Still, perhaps He has the dead-in-Satan digging the basin for the lake of fire.
The timing of when Hell is created and populated is far less important than the fact that it will be, as I indicated originally by terming my post merely as a point of order--that is, as a lighthearted technicality.
I don't know whether Hell exists yet, although it certainly will (I am not a universalist).Well, it certainly existed in both the Old and New Testaments.
Have you tried reading them?
