Yes, it does need to be dealt with.
Revelation 14 KJV
(11) And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
their /
they = the ones that received the mark of the beast.
It can be substantiated by other verses throughout scripture that their torment will continue.
There was a place prepared for blessing and rest of the righteous.
Matthew 25 KJV
(34) Then shall the King say unto them on his right hand (the righteous), Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
There was also a place prepared for the torment and unrest of unfaithful spirit beings (angel, devil, demon).
Unfaithful humans will join them.
Matthew 25 KJV
(41) Then shall he say also unto them on the left hand (the wicked), Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
(46) And these (the wicked) shall go away into everlasting punishment: but the righteous into life eternal.
Demons/devils were not anxious to go to that place.
Matthew 8 KJV
(29) And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?
But they, along with unfaithful humans will share the same fate in time.
The beast and false prophet are sent to that place.
This happen
before the 1000 years Satan is bound.
Revelation 19 KJV
(20) And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
And
after the 1000 years, Satan is sent to that place.
Revelation 20 KJV
(10) And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
(And as Steko has already pointed out in a previous post, the beast and false prophet are
still there --- ie. have not been annihilated.)
And we have this:
Matthew 10 KJV
(28) And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
This is the word
Gehenna.
It is actually two words combined (valley/gorge & Hinnom) --- Valley of Hinnom.
The valley of Hinnom was the Hebrew name of a valley near Jerusalem in the OT where a wicked king practiced child sacrifice and erected idols of pagan gods (2 CH 28:3).
For this reason, it was considered an unclean place of the accursed.
For such a place, it was used as a dump to discard trash.
Jesus uses this
same word several times to provide a stunning visual of the place of "trash" (ie. unfaithful) being
continually burned.
A fitting visual description that they people could associate with, for
Gehenna was known as a place that
continually burned because it was never without trash there.
- Matthew 5 KJV
(22) But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
- Matthew 5 KJV
(29) And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
(30) And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
- Matthew 18 KJV
(8) Wherefore if thy hand or thy foot offend thee, cut them off, and cast them from thee: it is better for thee to enter into life halt or maimed, rather than having two hands or two feet to be cast into everlasting fire.
(9) And if thine eye offend thee, pluck it out, and cast it from thee: it is better for thee to enter into life with one eye, rather than having two eyes to be cast into hell fire.
- Matthew 23 KJV
(15) Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves.
- Matthew 23 KJV
(33) Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?
- Mark 9 KJV
(43) And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched:
(44) Where their worm dieth not, and the fire is not quenched.
(45) And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell, into the fire that never shall be quenched:
(46) Where their worm dieth not, and the fire is not quenched.
(47) And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire:
(48) Where their worm dieth not, and the fire is not quenched.
Which also takes us to the story of Lazarus and the rich man.
Luke 16 KJV
(24) And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame.
There will never come a time in this place when the wicked are not being tormented by the flame, the flame that will not be quenched.
Nowhere in scripture is it ever said that this flame will be quenched and that there will come a time when there will no longer be anything existing there to burn.
The flame that torments will exist forever.
