Scripture speaks of a final place of judgment known as the "lake of fire."
Then the beast was captured, and with him the false prophet who worked signs in his presence, by which he deceived those who received the mark of the beast and those who worshiped his image. These two were cast alive into the lake of fire burning with brimstone (Revelation 19:20).
And the devil, who deceived them, was cast into the lake of fire and brimstone where the beast and false prophet are. And they will be tormented day and night forever and ever. . . Then Death and Hell were cast into the lake of fire. This is the second death. And anyone not found written in the Book of Life was cast into the lake of fire (Revelation 20:10,14,15).
But the cowardly, unbelieving abominable, murders, 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 (Revelation 21:8).
The Scripture has the following to say concerning the lake of fire.
The lake of fire is also known as the second death
Blessed and holy is the one who has part in the first resurrection. Over such the second death has no power (Revelation 20:6).
The judgment of the lake of fire is final, conscious, and bodily. From these passages we can make the following observations.
1. The second death is eternal death from which there is no hope. The lake of fire is the final destination of unbelievers. Those who had been kept in Hades will eventually be placed in this eternal judgment. The second death is equivalent to saying the last death.
2. Those suffering are conscious (Revelation 20:10). The suffering is eternal, the dead are not in a state of extinction.
3. The wicked are suffering in bodily form. There will be a resurrection of the unbelieving dead in some type of bodily form. Jesus said.
Do not marvel at this; for the hour is coming in which all who are in the graves will hear His voice and will come out - those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of condemnation (John 5:28,29).
I have a hope in God - a hope that they themselves also accept - that there will be a resurrection of both the righteous and the unrighteous. (Acts 24:15).
If the dead were merely annihilated, then there would be no reason for a resurrection. Furthermore if they were in their final place of judgment in Hades, there would not be a need for a resurrection.
4. The lake of fire is referred to as a burning lake. Four times fire and sulfur are mentioned in the Book of Revelation (Revelation 14:10: 19:20; 20:10 and 21:8) when referring to the lake of fire.
What is commonly known as hell, is what the Bible calls the "lake of fire." It is the final judgment of the wicked. Those in the lake of fire will suffer eternally, consciously, and bodily. It will be an awful place.
