The eternal fire was prepared not for man but for the devil and his angels.
You are doing well in holding to the text which has lead you this far, but these people need to relate to the secular world they live in before the source of your kniwledge, the Bible, has any importance for them.
Once they see the devil as the Great Harlot whose Feminists' 1960 Sexual Revolution turned a God fearing America into a weak, aborting Welfare-funded Matriarchy, one using the shock troops of Gayness to advance a socially dstructive sexual promiscuity that is bankrupting the Nation, then the Bible prophecies can be explained:
.
Rev. 17:3
So he carried me away (in the spirit of thought),
into the wilderness (of my imagination)
and I saw (as if)
a woman, ...
.... (those who have Institutionalized a system of sexual seduction into a failed matrimony),
sit upon a scarlet coloured beast (of a brazen and corrupt sexually misdirected economic system: [Dan 3:1-5]),
full of names of (Pagan)
blasphemy, having seven heads:(which existed in (1) Egypt, (2) Assyria, (3) Babylon, (4) Persia/Mede, (5) Greece, (6) Rome (7) the whole of Western Culture to follow)...
... having ten horns upon these seven heads:(1. Undivided Empire; capital Rome: [305 AD],
2. Western Roman Empire: (Romulus Augustus): [to 476 AD],
3. Eastern Roman: Byzantine Empire, [1453 AD]
4. Charlemagne, [800 - 1000 AD]
5. Holy Roman Empire, [1200 AD-1492 AD]
6. Italy, [Renaissance, 16th century]
7. Spain, [17th century]
8. France, [18th-19th Century]
9. Britain, [19th-20th century]
10. Nazi Germany, [20th century])
11. America next?
