Universalists I have come across commonly state that the lake of fire is not a place of eternal duration but of temporal duration. It may last an age and then those in it will get out as they have come to faith in Christ because the fire is not a punishment but a correction. John uses “forever and ever” or in the Greek “eis tous aiōnas tōn aiōnōn” to describe not something temporal in duration but of something that is eternal in duration something that’ll never come to an end. To say otherwise could actually be considered heretical. Keep reading to see what I mean :
Revelation 20:10 is our target passage as it does one of two things. It first establishes that when Jesus uses “aiōnios” in Matthew 25:41 to refer to the eternal fire that is prepared for the devil and his angels that the wicked will be thrown into aiōnion does mean eternal. Secondly, to show that those who go in the lake of fire never get out but will be tormented for eternity.
Revelation 20:10 reads :
“and the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever.”
Now let’s see how John uses this phrase “eis tous aiōnas tōn aiōnōn” translated as "forever and ever" elsewhere in Revelation to see how he uses it and if it is translated correctly :
In Revelation 1:17- 18 : “When I saw him, I fell at his feet as though dead. But he laid his right hand on me, saying, “Fear not, I am the first and the last, and the living one. I died, and behold I am alive forevermore, and I have the keys of Death and Hades.”
Jesus said that he died and is alive forever more. Is Jesus actually alive forevermore or will he die again? However long Jesus is alive for is how long those in the lake of fire will be tormented. We also know that the translators are correct in their rendering of this as “forever and ever” because this is further supported by Romans 6:9 which reads
“We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him.” - Romans 6:9
Revelation 11:15 : “Then the seventh angel blew his trumpet, and there were loud voices in heaven, saying, “The kingdom of the world has become the kingdom of our Lord and of his Christ, and he shall reign forever and ever.”
Will God reign forever and ever or will his reign eventually end? However long God reigns for is how long those in the lake of fire will be tormented for.
Luke 1:33 says : “and he will reign over the house of Jacob forever (eis tous aiōnas) , and of his kingdom there will be no end.”
If Jesus’ kingdom will have no end that means it is eternal. Just like Revelation 11:15 says. This just adds further support that John is speaking of an eternal duration of something that has no end and not of something that does have an end. That is not how John in Revelation uses “eis tous aiōnas tōn aiōnōn”.
Revelation 10:6 : “ and swore by him who lives forever and ever, who created heaven and what is in it, the earth and what is in it, and the sea and what is in it, that there would be no more delay”
Either God lives forever and ever or he does not. However long God lives is how long those in the lake of fire will be tormented for.
John has used eis tous aiōnas tōn aiōnōn to describe how long God lives in Revelation 15:7 ; 7:12 ; and 4:9-10. Everyone knows that God lives forever and ever. In this same book we see God being called “the first and the last”, “the beginning and the end” , “The Alpha and The Omega”. These are all titles for an eternal being. Also we have many passages such as 1 Timothy 1:17 and 6:16 that refer to God as immortal which would mean that he can’t die and would live forever and ever like is translated correctly here in Revelation and in those passages.
Romans 1:23 : “and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.”
God is described as immortal which means that he will live forever and not die. Which is exactly what John is describing in the passages referenced in Revelation. To deny that God lives forever is heretical.
Revelation 22:5 : “And night will be no more. They will need no light of lamp or sun, for the Lord God will be their light, and they will reign forever and ever."
However long the reign of the righteous or the saved lasts in the Kingdom or New Jerusalem is how long those in the lake of fire will be tormented for. Are we really going to say that those in the New Jerusalem won’t reign for all times? I don’t think any Universalist would say that they would be kicked out of heaven?
With all of this aforementioned proof from the book of Revelation demonstrating that “eis tous aiōnas tōn aiōnōn” does indeed mean forever and ever and is correctly translated. We can see that those in the lake of fire will be there not for one age and then will be let out after some “correction” but they will be there for eternity like it is correctly translated in basically all translations into english. Those thrown into the lake of fire will never leave. This also proves that when Jesus used aiōnion in Matthew 25:41 to refer to the lake of fire that was prepared for the devil and his angels is indeed eternal which would also mean that Matthew 25:46 also means eternal in duration.
Matthew 25:41,46 : "Then he will say to those on his left, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels. And these will go away into eternal punishment, but the righteous into eternal life.”
Revelation 20:10 : " and the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever.
Revelation 14:9-11 : "And another angel, a third, followed them, saying with a loud voice, “If anyone worships the beast and its image and receives a mark on his forehead or on his hand, he also will drink the wine of God's wrath, poured full strength into the cup of his anger, and he will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment goes up forever and ever, and they have no rest, day or night, these worshipers of the beast and its image, and whoever receives the mark of its name.”
