Aguest:
You raise some interesting points. Thank you for sharing your thoughts. One point, though. John received his revelation when in exile on Patmos when he was a very old man....well after the death of Paul. So, John could not have been the "man" that Paul referred to...unless John had an earlier revelation from God and shared it with Paul. The fact is that some Bible scholars think that Paul was using a literary form to describe his own experience.
Another question I have is the period of the 1000 year reign. The Bible seems silent on any specifics. It implys that there are "nations" existing when Satan is let loose. (Rev. 20) Do these people live and die as experienced now? Are these nations comprised of survivors of Armageddon and their progeny? The difficulty of interpreting Revelation is that it is not necessarily written in a "one deminsional" chronological order...as you aptly pointed out. This makes it difficult to be dogmatic on the events that are described. It is hard to reconcile that the "camp of God's people, the city he loves" is the same as the New Jerusalem that comes down from heaven. On the one hand, the "camp, city" results in the destruction and annihiliation of Satan and his hordes. But descent of New Jerusalem ushers in peace, harmony and life.
There still remains too many questions to be dogmatic.
