Maybe I should clarify what I'm meaning by a literal place. I'm meaning in a realm that we are not familiar with, have not seen, and that within this realm spirits can be literally imprisoned in a literal place of some kind.
Let's say it is a literal place of some kind. What we should not do is assume that such a place is no different than a physical place on earth. Like you said, we are not familiar with the spirit realm. We can't see it and we should not pretend to know exactly what it's like because we don't. We know that it's not a physical place as in a literal, physical bottomless pit or physical prison because it talks about non-literal entities like a beast, a dragon and locusts being imprisoned there. Whatever that literal place would be, it's not a literal bottomless pit. A non-literal beast, dragon or locust cannot be imprisoned in a literal bottomless pit. The whole descriptions of a beast, a dragon and locusts being imprisoned in a bottomless pit is symbolic. The beast, the dragon, the locusts, the chain, the bottomless pit are all symbolic entities. What that all symbolizes is what we need to determine. For Amills, it symbolizes restraint from doing certain things and is not to be compared to being physically chained up in a physical prison where someone is completely incapacitated.
In the case of the locusts in terms of what is described in Revelation 9, they are not completely incapacitated in some literal place where they can do nothing. No, it's not literal locusts. So, it's talking about fallen angels being restrained from doing something. What is that? Well, based on Revelation 9, they are restrained from tormenting all of those who don't have the seal of God to the point of making them want to die. In no way, shape or form does it indicate that they are literally incapacitated while in the bottomless pit and unable to do anything at all. That's what you need to understand about the dragon (Satan) and the beast being in the bottomless pit as well.
What about when someone lost dies, per your view? If spirits can't be imprisoned in some literal place, what is preventing the lost from roaming around wherever they care to? Maybe they want to hang around on the earth? What would be preventing them from doing that if there is no prisons in the spirit world capable of imprisoning any spirits?
Look, I'm not saying there can't be a literal place of some kind where spirits are contained and unable to roam around or do anything. I believe hell is a literal place and that's where the spirits of unbelievers are. Can I describe what that's like or what that means exactly? No, none of us can. I'm simply saying that is not what is indicated in relation to the bottomless pit which is not a literal bottomless pit. It's not any more literal than the beast, dragon or locusts cast there.
We can see that the locusts do a certain thing when released from the bottomless pit. We can see the dragon, Satan, doing a certain thing when released from the pit. Nowhere in these verses that talk about entities being released from the pit that it mean they formerly were not able to do anything at all and now are able to do whatever they want. No, in the case of the locusts (fallen angels), they formerly were not able to torment those without the seal of God to the point of them wanting to die, but once released from the pit, they are able to do so.
Have you thought about interpreting that in light of verse 13? Doesn't verse 13 tell us what is meant by death and hell that it is meaning them that were in them? Therefore, when death and hell get cast into the LOF it could be another way of saying those that were in death and hell get cast into the LOF.
Actually, I have thought about that, but it would be redundant if that is what it meant since verse 15 talks about those whose names are not written in the book of life being cast into the lake of fire. The dead being judged in verse 13 are those whose names are not written in the book of life, so death itself is differentiated from them. Also, what exactly would that mean for hell to be cast into the lake of fire? Is the lake of fire bigger than hell, so you can just kind of dump hell into it? Come on. No, that's absurd and not what it's saying.
Also, have you considered comparing to the following?
Revelation 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Sounds like to me all these fit someone that were in death and hell, thus the death and hell cast into the LOF per Revelation 20:14, where that verse also says it is the 2nd death.
Again, if that's what it meant it would make verse 15 redundant.
IOW, because they are not literal locusts, this means there is no one to cast into anywhere, especially somewhere literal?
Yeah, that's what I'm saying. Unless you can explain how non-literal locusts can be cast into a literal place? Can you? If the locusts are not literal it only follows that the place that are cast into is not literal either. Could the bottomless pit symbolize a literal place of some kind? I suppose it could. But, I don't believe it does because in none of the cases where it describes things being in the bottomless pit does it say that it makes them completely incapacitated and unable to move around or do anything at all.
Yet, what does that have to do with anything since these locusts obviously symbolize something literal? IOW, they literally exist in some form except they are not literal locusts.
Yes, of course. They symbolize fallen angels. But, my point is that they are described as non-literal locusts imprisoned in a bottomless pit. If the locusts themselves are not literal, which they are not (they instead symbolize something literal), then these symbolic locusts should not be seen as being in a literal bottomless pit. Instead, the bottomless pit is symbolic just as the locusts are.
2 Peter 2:4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
Maybe this verse explains some of this?
Think about what that verse is saying. Should we take that to be saying that the fallen angels are literally chained up and unable to do anything? We know that can't be what it means. The fallen angels/demons would love nothing more than for people to believe that so that they can freely go around trying to deceive people who think they are just chained up somewhere and unable to do anything.
By the way, the Greek for translated as "hell" in that verse is not the hell that other scriptures speaks about, which is Hades, the place where the spirits of dead unbelievers go. The Greek word translated in that verse as "hell" is tartaroō, which in English is called Tartarus. Clearly, fallen angels/demons have not been literally chained up since they fell since they've been plenty active deceiving people and even possessing some people for many years.
