Revelation 21:4

4 God will wipe away every tear from their eyes; and death shall be no more, neither shall there be anguish (sorrow and mourning) nor grief nor pain any more, for the old conditions and the former order of things have passed away.

Here is the Truth about the Lake of Fire being an eternal suffering place for the unsaved. We have been shown that our Father will make His abode among men, remember Jesus said men, not just saved men. We are shown that our Father wipes away every tear from men, there is no more death with men, there is no anguish among men, no sorrow, mourning, grief, or pain among men. We are shown plainly that the old conditions will pass away. So all pain, grief, sorrow, anguish, mourning, and tears shall be done away with after Judgment Day. If this verse is true, what are men suffering in the Lake of Fire? All of these things have passed away from mankind, not just saved men. If someone is thrown into the Lake of Fire, do they become something other than a human?

The Truth is the Lake of Fire destroys spirit, soul, and body. Anyone or anything that is thrown into the Lake of fire is totally done away with. This is why Jesus told us that we are to fear Him Who is able to destroy body and soul, Matthew 10:28. We are only shown that satan, the anti-christ, and the false prophet suffer eternally in the Lake of Fire, and they do, because they are not human! 

It is a great study, and I highly recommend that you do it. Go and read just what the Bible teaches on the eternity of Hell and the lost. If the lost were to suffer eternally, it would be a suffering that did not include tears, pain, mourning, grief, or anguish. And they would have eternal life, and Jesus tells us that the only way that a person could have eternal life was to be born again of Him, John 6:51. There cannot be an eternity in the Lake of Fire for men and these verses still be true.

As the cloud is consumed and vanishes away, so he who goes down to Sheol (the place of the dead) shall come up no more. Job 7:9

Behold, they are like stubble; the fire consumes them. They cannot even deliver themselves from the power of the flame [much less deliver the nation]. There is no coal for warming or fire before which to sit! Isaiah 47:14

Such people will pay the penalty and suffer the punishment of everlasting ruin (destruction and perdition) and eternal exclusion and banishment from the presence of the Lord and from the glory of His power, 2 Thessalonians 1:9 (Our Father is Omnipotent. How can someone be cast out of His presence? They only can if they cease to be.) 

FOR BEHOLD, the day comes that shall burn like an oven, and all the proud and arrogant, yes, and all that do wickedly and are lawless, shall be stubble; the day that comes shall burn them up, says the Lord of hosts, so that it will leave them neither root nor branch. Malachi 4:1
