The Bible as we know it has been translated from various languages which were mainly pictures that were put into words.
Pictures had many meanings and the picture word Nephesh, meant soul, breath, spirit, etc. When people talk about a spirit leaving the body, they visualize that there is now a ghost floating around whilst if somebody said the breath left the body, nothing is really being visualized and thought about it. God breathed on Adam and that is why he became a "living soul". With regards to the dead people now, there are no souls/spirits flying around representing those bodies. God has the power to resurrect those bodies no matter where the dust is, whether in the grave or in the sea and to give them their eternal bodies or, to raise them for final destruction. The hell word derived from the picture word Sheol which also means, grave, hell or pit. Everlasting comes from the picture word Ad which means even to, for, into, so long as, so that, till, toward, until, everlasting, eternity, ever, evermore, old, perpetually etc. So to say that the fire will be everlasting is questionable. It could be that the fire will be there until everything has been destroyed that needed to be destroyed and then will die off. This will make more sense as there cannot logically be a hell burning with people and Satan and his angels screaming, shouting and swearing forever while there is a new earth with saved people, God and His angels and Jesus living in harmony on the same earth. I believe that Satan, his angels and the resurrected unsaved will be devoured by fire and brimstone, each one's time before total destruction linked to the severity of his/her sins and Satan will be the last to be devoured. The eternity connected to this will be up to the point where he/she looses consciousness up to which time it felt for ever, just before total destruction. After the mass destruction, a new heaven and earth will be created and a new life will begin for all the saved, angels, God and Jesus on this new earth. When the world was destroyed with water, everybody did not believe that it will happen but Noah and his family was saved. People today might believe that the world will not be destroyed by fire and brimstone from heaven, but this earth will be destroyed by it and like Noah's Ark floated on the water, so will the New Jerusalem float on the lava before the New Earth is created.
