The Judgement Day Fire is the Source of reality resetting our environment back to Eden; if we study all the contexts in the world's religions as one, we can see that it is a cleansing fire, where those that are aligned with the things of God will pass through it, those who are not holy will be incinerated.

It doesn't happen in some other place as scholars have tried to re-emphasize; instead it comes on this whole reality in a single day, and then it restores here back to Eden at the same time (Joel 2:3).
