objectivetruth - They do seem to be the same event. On the JW aspect, since they take Ez 38/39 to be about them and really disgarding most of what those chapters say to mean governments will turn on them after false religion then armageddon, is that if they are the same event, then it happens at the END of the 1,000 year reign according to Revelation.
Also it does not show a wiping out of everybody either.
In Ez 39:27-28 it says how God had 'concealed' himself. (which would answer those who ask where he is and why isn't he making himself obvious), and he uses this event to 'santify himself before the eyes of many nations'. Other scriptures show only those attacking them are destroyed by the fire from heaven. The world is a witness to this event.
Revelation 19 is one example of how so called armagedon may not be a one time event. In chapter 19 did that event ever happen? In 19:19 the wild beast and kings of the earth and their armies gathered and when the one seated on the white horse defeats them the wild beast and false prophet are tossed into the lake of fire. Everyone else is killed by the one seated on the horse.
In Rev 20, it shows after 1,000 years satan is let loose, gog and magog gather for war, surround camp and fire comes down and destroys them, and the devil is tossed in the lake of fire, where beast and prophet from previous worldevent already were at.
Gotta do more research but that does show 2 events. The specific event of Ez 39 and Rev 20 could be the same at the end of the 1,000 year reign but without digging up a lot of notes I have, I took Ez 39 and Rev 19 to be the start of the 1,000 year reign and Rev 20 to be the end, although still a chance to me they are speaking about the same event. I took into consideration other books such as Zephaniah, Zechariah, Jeremiah, etc.
