Well, it destroys your reasoning. Hell and death are not people.
How does it destroy my reasoning when death and hell is never said to be cast alive into the LOF, while the opposite is true of the beast and fp? Come on now, only a living being of some kind can be cast alive into somewhere. That's plain ole' common sense even a 3rd grader should be able to comprehend. That if something is alive and being cast into something, it means it is a living being of some sort.
For example. A fisherman casts his net into a lake. Later on he checks his net and there are some fish in
it he has no use for, so he casts these fish back into the lake.
That then would equal this, assuming the fish are still alive that he casts back into the lake.
Initially he casts his net into the lake.
Later on he casts unwanted fish back into the lake. IOW, these fish were cast alive into the lake.
Can you not see per this analogy only a living creature of some kind can be cast alive into somewhere? It would be pretty silly to say that the net is cast alive into the lake. Maybe the one casting it into the lake would be alive, the net certainly wouldn't be, though.
Doctrinal bias is the only thing that can explain why anyone could insist that something cast alive into the LOF, that it is not a living being of some kind. If not doctrinal bias, what then? That the person is not reasonable, thus someone that can't be reasoned with? This person is not remotely using Scripture to interpret Scripture in this case, because if they were, they would not be using Revelation 20:14 to interpret Revelation 19:20, they would be using Revelation 20:10 to interpret Revelation 19:20. No reasonable person that can be reasoned with could or would remotely think, if something is cast into the LOF alive, that this means this something cast in is not even a living being of some sort.
