IF you are asking about the 'last' fiery furnace that destroys the 'soul/spirit' entities of all the unrepentant rebels? That 'fire' pit has yet to be 'created', only the devil and a few of his henchmen have to date been judged to be erased (destroyed from within) forever. Judgment Day for every one else won't take place until final exams are taken. Exams follow required mandatory classes of the A B C's of the Creator and HIS perfection without the ugly evil influence of the first rebel narcissist.
I mean, the current, operational Hell. Unless you’re saying there isn’t any yet, which is directly opposed to the other poster’s assertion that it has already been made.
