Revelation was not given to us in the same order as John experienced it!
John had to take the visions and turn them into a "mystery". When the 7th trumpet
sounds...this mystery of God will end.
seal not the sayings of this book/
as in, don't hide the order for the last part of Revelation
Seal not the messages revealed in the little book that John had seen!
It seems to me that your have made some very bold claims concerning the Book of Revelation.
For me, Revelation can be broken up into topics, presented in no specific order, where the topic can span the breadth in time of the seventh age and in Rev 16, the time span is much greater as it now reaches back into man's past history all of the way to the acts just before the final judgement.
For me, words have meaning and unfortunately our translators have confused the Greek Word "seismos" which actually has the meaning of "turmoil" in our English and not 'earthquakes" as the translators have translated this Greek word into English whereas the meaning of the Greek word "seió" is more representative of an earthquake. The Greek word "seismos" is found in Matt 8:24 where it is describing the turmoil in the sea, where the waves were rising up as standing wave and in danger of flooding the boat such that it would sink.
Christ in response to the fear of the disciples of the turmoil in the waves commanded the wind, which was causing the size of the wave to grow, to cease, thereby removing the driving force in the creation of the waves in the lake. If the translators had been consistent in their translation in Matt 8:24 then they should have used the word "earthquake," to describe what was occurring in this case as well.
From my examination of this work as used in the New Testament, I believe that it would be better to use the English word "turmoil" to describe what was occurring when it was used. How does an Angel, descending from heaven to roll away the stone over the entrance of the tomb, cause an earthquake as he descends, However, there was great turmoil among the guard when they saw the angel descending and in their fear at what they were seeing, they ran away from guarding the tomb. In Matt 8:24 how can you have an earthquake in a body of water.
Your OP premise, from my understanding, does not line up contextually with what has been conveyed to us by John in the book of Revelation.
