It's difficult to follow what you are saying, though the little I can follow, 'sounds' like you have seen/noticed something about the language difference between for example "a throne" when it's first introduced and "the throne" when it's mentioned again, and "seven angels" when they are first introduced, and "the seven angels" when they are spoken about again.
You seem to be saying that it explains, or goes a long way to explain the "when" of whatever is being written about, is happening.
But I need to be spoon-fed and you're expressing the understanding you already have in your mind without adequately putting it into English, text-book style, as in fact A leads to fact B leads to fact C because what you have said so far is almost as 'cryptic' as the Revelation itself.
Revelation 15:1
"And I saw another sign in heaven...seven angels..."
15:7
"And one of the four beasts gave unto the seven angels..."
John saw - another sign, so at least one other sign in heaven must
be placed ahead of this one on the overall timeline of events. He saw
-the four beasts, so we know that the scene in Rev. 4 happens first, because
that is where John marked his first point of them.
Rev. 4:6 KJV
"And before the throne...a sea...in the midst of the throne, and round about the
throne
were four beasts..."
What I'm wanting us to study is that Rev. 15:1 was actually written by John before he
ever saw the time of Rev. 8:2.
Rev. 15:1 refers to -another sign in heaven
So, let's find the very first one that John had revealed to him.
Rev. 12:1
"And there appeared a great wonder in heaven..."
Rev, 12:3
And...appeared another wonder in heaven..."
Rev. 15:1
"And I saw another sign in heaven...seven angels..."
This was all shown to John before he ever had the things in Rev. 8
shown to him. Revelation 8:2 has - John referring to that set as now
-the seven angels.
Why is this section of Revelation jumbled with hidden parts? Because
John had to make a mystery that ends at the time of the 7th trumpet.
the mystery of God
This will finish as was declared to the prophets. It will end early. God will
repent...call back some of the trouble that was to take place.
Rev. 10:7
"But in the days of voice of the seventh angel, when he shall begin to
sound, the mystery of God should be finished, as he hath declared to his
servants the prophets."
In this chapter, John will take and eat a little book. This little book is where
we get the final chapters of Revelation from, and it was not made into a mystery.
John was told that he was to prophesy again - must prophesy again, and later told
not to seal the sayings in Rev. 22:10.
seal not the sayings
