The lake of fire passages, in context.
Revelation 2:11 He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death.
Revelation 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Revelation 19:20 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 1000 years later, the beast and the false prophet, who is a person, are still in the lake of fire.
Revelation 20:10 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.
Revelation 20:14 And death and hell were cast into the lake of fire. This is the second death.
Revelation 20:15 And whosoever was not found written in the book of life was cast into the lake of fire.
Revelation 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
The lake of fire [LOF] is called “the second death” twice in Rev. vss. 20:14 and 21:8. While this is true, Rev. never says that anyone is thrown into the LOF then they die. The terms the “lake of fire” and “ the second death” are interchangeable, “the lake of fire” is “the second death” and the “second death” is “the lake of fire,” thus we can see that it is not synonymous with death or destruction.
.....We also see that being thrown into the LOF is not synonymous with death from Rev 19:20, where the beast and the false prophet, who is a person, are thrown into the LOF and 1000 years later in 20:10 the devil, is thrown into the LOF. Three living beings, are thrown into the LOF but they do not die, they are tormented day and night for ever and ever. There is not one verse in Revelation which says anyone or anything is thrown into the LOF then they/it dies.
.....Rev 20:14 says death and hell were cast into the lake of fire. Death is the point in time end of life, it has no physical presence and cannot be literally thrown anywhere. Since neither death nor hell could or have died a first death they can’t die a second death. But there is a scriptural answer which does not involve jumping through hoops mixing literal and figurative in one sentence, there is a death and hell which can be thrown into the LOF.
Revelation 6:8 And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
The angel of death and the demon of hell are thrown into the LOF and their power to kill ended.
.....More verses which show that the LoF is not synonymous with death or destruction. Rev 21:4 says “there shall be no more death” in vs. 5 Jesus said “Behold I make all things new.” “No more death””all things new” but 3 verses later Rev 21:8 says certain groups “shall have their part in the lake which burns with fire and brimstone: which is the second death.” If vs. 4 is correct then those mentioned in vs. 8 do not die.
Revelation 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
Revelation 21:5 And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.
Revelation 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
