Hello. I believe scripture. There are verses used to talk about eternal suffering which I think are misread: Rev. 14:10-11. These are talking about humans who took the mark of the beast. It does not say they are thrown into the Lake of Fire. The LOF comes after the 1,000 year reign of Christ on earth.
They are thrown in a place of torment, a realm, where they have no rest day or night. Verse 11 simply states "the smoke of their torment ascendeth up for ever and ever." Now, they may be suffering but scripture says it is the smoke of that realm that ascends forever. I think this describes the place many call hell or even hades.
We are told much later that hell/hades gives up the dead/lost in it and those not found in the book of life go into the Lake of Fire. This is known as the second death for humanity.
Now, what is death like in the LOF? I believe scripture at least says Satan will be tormented for ever and ever in it. So MAY be the beast and the false prophet which were the first to be thrown in when Christ returned.
However, I am not so sure whether the life of the living souls of humanity will remain inside or be consumed back into God who is life and the giver of life. If he giveth, he can taketh back. Here is my reason/theory/speculation.
I believe God created mankind's body out of the elements called ground. Same elements from which the earth was formed. God cursed the ground when Adam/Woman committed their sin. The process of death over time came unto mankind and the earth also began to wear out like an old garment. This was done obviously for a big reason.
God's first command to humanity was to multiply and reproduce. He was growing himself a family. Since birthing was a process over time so would death need to be so that multiplying and reproducing would continue. Now, I think God allows humanity to live until he is ready to end multiplying and reproducing. The way to accomplish this long suffering time is to have store houses for holding the living spirits of mankind. For them he has named some of his barns. 1. the bosom of Abraham, the place of heat and torment/hell, the place Christ goes to prepare for us, and finally the Lake of fire.
Satan and his take a different route, cast out/down and commanded to partake of the dust of the ground forever, but still with access to God, chained in 'the Pit/Abyss.' And finally the Lake of Fire.
Now, at approximately the same time Satan and hell's content are cast into the LOF the earth is made new again. That means there are no longer any cursed ELEMENT OF THE GROUND LEFT... all is made new.
I believe it is at this time that mankind looses its physical identity when the body of his soul is destroyed and that God, who is life and the giver of life, takes back that life into his own eternal infinite self from which it came. This may very well describe the SECOND DEATH for mankind.
This is why I don't think mankind suffers forever in the Lake of Fire. He is gone.
Now, for Satan and the beast and false prophet ... well, that's another topic.
