Here in scripture is the lake of fire mentioned:
NKJV Revelation 20:13-14. The sea gave up the dead who were in it, and Death and Hades delivered up the dead who were in them. And they were judged, each one according to his works. Then Death and Hades were cast into the
lake of fire. This is the second death.
NKJV Revelation 21:8. But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the
lake which burns with fire and brimstone, which is the second death."
When molten magma comes to the earth's surface, it turns into lava, which dries. Molten magma beneath the earth's surface continues to burn. This is the only lake of fire on earth!
The lake of fire may be a real place or a metaphor as scripture gives no literal location, but is very descriptive as a place of outer darkness and torment and being eternal as all those people including Satan, the beast and the false prophet that are cast into it will be remembered no more.
The duration of punishment for the one cast into the lake of fire is everlasting. Isaiah speaks of the everlasting burning of the fire that shall never be quenched and of the worm which shall never die (Isaiah 33:14; 66:24). David said that some would awake unto eternal life and others unto shame and everlasting contempt (Daniel 12:2). John the Baptist and Jesus spoke of the unquenchable fire (Matthew 3:12; Mark 9:43). Paul the Apostle speaks of how the lost will be punished with everlasting destruction from the presence of the Lord (II Thessalonians 1:9).
The Apostle John says that the smoke of their torment ascendeth up for ever and ever; and they shall have no rest day and night; and they shall be tormented day and night for ever and ever (Revelation 14:11; 19:3; 20:10). Jesus said that the lake of fire is a furnace of fire in Matthew 13:41, 42 and outer darkness in Matthew 22:13.
The fact that the lake of fire is eternal is plain from the following verses where it is described as:
1. Everlasting fire.......................Matthew 25:41
2. Everlasting punishment...........Matthew 25:46
3. Eternal damnation..................Mark 3:29
4. Everlasting destruction.......... II Thessalonians 1:9
5. Everlasting contempt..............Daniel 12:2
6. Torment forever and ever.......Revelation 14:9-11
7. Blackness of darkness forever.....Jude 1:13
8. Vengeance of eternal life............Jude 1:7
9. Lake of fire--forever and ever......Revelation 20:10
10. Second death--forever..............Revelation 20:14
11. Elements melt, earth and works are burned up.......2Peter Chapter 3
God gives us a description as in fire and brimstone which can be used literal as in Sodom and Gomorrah burned to ashes and as a metaphor for torment, suffering, punishment or as Matthew 8:12 describes it as outer darkness. The New Testament description is a bottomless pit (abyss) (Revelation 20:3), a lake (Revelation 20:14), darkness (Matthew 25:30), death (Revelation 2:11), destruction (2 Thessalonians 1:9), everlasting torment (Revelation 20:10), a place of wailing and gnashing of teeth (Matthew 25:30), and a place of gradated punishment (Matthew 11:20-24; Luke 12:47-48; Revelation 20:12-13), everlasting fire Matthew 25:41, everlasting punishment, Matthew 25:46, lake of fire burning with brimstone.
Jude 1:7 clearly states an example of eternal fire. This is the same Greek word that is used for everlasting fire and everlasting punishment as used in Matthew 18:8 and Matthew 25:41,46 (Notice: The place, as no real name is given, where the unsaved go is everlasting punishment, and not everlasting punishing. The punishment is eternal in its results, not in its duration. Unquenchable fire is a fire that cannot be quenched or put out until everything in its path is burned up.
In my own minds eye I see the lake of fire as a place where those who have rejected God, whether they be good or bad people, burning in a torment (fire and brimstone could be a metaphor for torment) of having to see those who have heard the call of God and have accepted Him and now live in a place of paradise with all the fullness of God in all His glory. No more tears, no more hurts, pain sickness, etc, etc. Those in the lake of fire are outside the realm of God continuing in all their sin, sickness, hurts, pain tears, etc. etc., but can see those who are in the glory of the Lord like looking through a window and wanting what others have, but will never have it and this is their torment for eternity as they are constantly consumed with the fire that burns in their souls for what they have rejected and now to late to receive.
2Pe 3:5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
2Pe 3:6 Whereby the world that then was, being overflowed with water, perished:
2Pe 3:7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
2Pe 3:8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
2Pe 3:9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
2Pe 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
2Pe 3:11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
2Pe 3:12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
2Pe 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
