Hi KML,
I suggest to distinguish between „hell“ and "the lake of fire“ - according to the bible. They are not identical. Hell is a temporary place lasting until the great white throne judgement. Then those therein will come out and be judged. Everyone not found in the "book of live“, will be thrown into the lake of fire (Rev 20:15). The false prophet and the antichrist will be thrown directly into the lake of fire without passing hell. (Rev. 19:20). In the end, death and hell itself (probably with remaining demons and fallen angels) will be cast into the lake of fire (Rev. 20:14). Forever. The location of hell and lake of fire not necessarily need to be the same - don’t know...
Blessings!
