Fire coming down from heaven and consuming people is a pretty clear sign of divine disapproval. It happened several times in the Old Testament: to Aaron’s sons, to the soldiers coming after Elijah, and to Sodom and Gomorrah. However, those were relatively small incidents compared to the massive flame that pours down from heaven at this moment — so many men, in just a few seconds, and with not so much as a word being spoken. They are devoured by fire.
Then the devil, seemingly without even a scuffle, is hurled into a very nasty lake. This lake is like no other and is described as having two components: fire and brimstone. Of what exact composition these two are is another mystery, but that they are capable of making a powerful spirit like Lucifer suffer extremely, is beyond question. The place is horrific by anybody’s standards.
At least two others are already in that lake: the beast and the false prophet. There is no word of any kind of reunion, nor should there be. They all become mere occupants of this terrible and inescapable prison, and will suffer for their crimes against the Eternal One as long as He is. The enemy of our souls, and all who hitched up with him, are gone forever. This is good news.
At this point John sees a throne like no other that has ever been seen before. It is gigantic, dwarfing the rest of creation. It is white, displaying the universal color for purity and justice. It is imposing; so much so, that earth and heaven, almost as if they had personality, race away from it. They are tainted and useless, so they disappear from the scene.
These are fantastic moments, setting the stage for the best that is still to come
