Chapter 7 and 8 are not a consecutive chain of events. They are two descriptions of the same chain of events set in different terms.
I’m not sure what you think that would prove. It was in chapter 6 and the opening of the sixth seal that the men knew it was already the wrath of God. You had said the wrath of God didn’t start until the bowl judgments. They already knew it was the wrath of God during the 6 seal judgments as I showed in post 114. Chapter seven is simply explaining what was happening in heaven with saints there who already had come out of the “great tribulation” and then in Chapter 8 the seventh seal is opened.
