... from the righteous [50] and throw them into the blazing furnace, where there will be weeping and gnashing of teeth.
If I get tossed into a furnace I'll weep and gnash my teeth too.
John 3:12
I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things? [13] No one has ever gone into heaven except the one who came from heaven.
Isaiah 66
[22] “As the new heavens and the new earth that I make will endure before me,” declares the LORD, “so will your name and descendants endure. [23] From one New Moon to another and from one Sabbath to another, all mankind will come and bow down before me,” says the LORD. [24] “And they will go out and look on the dead bodies of those who rebelled against me; the worms that eat them will not die, the fire that burns them will not be quenched, and they will be loathsome to all mankind.”
The worms don't die and the fire won't die. Nothing in this says that people won't die.
Revalations 14:
[9] A third angel followed them and said in a loud voice: “If anyone worships the beast and its image and receives its mark on their forehead or on their hand, [10] they, too, will drink the wine of God’s fury, which has been poured full strength into the cup of his wrath. They will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. [11] And the smoke of their torment will rise for ever and ever. There will be no rest day or night for those who worship the beast and its image, or for anyone who receives the mark of its name.”
[13] Then I heard a voice from heaven say, “Write this: Blessed are the dead who die in the Lord from now on.”
“Yes,” says the Spirit, “they will rest from their labor, for their deeds will follow them.”
[11]- the smoke rises forever
