[/FONT][/SIZE][/COLOR]This is all certainly possible but why would he use the past tense in 1:9 regarding his time at Patmos?If he is on Patmos at the time of the writing this would be hard to explain linguistically.
this is also my point about the tense of the wording in rev.1;19,,,"hast seen,are,which shall be",,,could also raise the point that if he had already seen the destruction of Jerusalem it would be possible then the record found in the text regarding the destruction are things he had seen past tense.
so if we consider rev.1;19 any point in time could be the beginning point,,,so if it for instance was ad72 when he received the Revelation then the text would still read the same,,,
(1)=ad64,,,,saw Christ crucified past tense,,,he see's Nero present tense,,,see's the destruction of Jerusalem future tense
(2) if written in ad71,,then he saw the Crucifixion,reign of Nero,destruction of jer. past tense,,,see's himself at patmos,and others in tribulation present tense,,,and and the rise of a beast/two horned beast future tense.
so of the three tenses mentioned in rev. 1;19 (the present tense as to john when he received the rev.) seems to be the only tangible way to narrow down "when",,,and from their if we see in the text when was present tense to john then we can see past tense and future from that exact point in time.
"one is",,,as an example,,another 7 churches instead of 9 so we know it's after the earthquake,and after laodiicea is rebuilt,,,ect. but the present tense things to john at the time he received this.,,,,,now the beast in rev.17;8 that was and is not shall ascend out of the bottomless pit (future tense at the time john received rev.),,,so also in the present tense when he received this rev. the beast(that was an is not),,,,in the (present tense) at the reception of rev by john is in the bottomless pit,,,
so to resolve the identity of the beast that was and was not that will ascend(rev.13;12) will also reveal "when",because we are given all three tenses surrounding this beast and told that he ,,,"was not" at the time john received the Revelations,,,but im as curious as you as to what others have also seen in regards to this so i will watch for a while,,,,,
