I found the four storylines in the Book of Revelation and have named them:
The Seals Storyline, Chapters Five through Eight
The Trumpets Storyline, Chapters Eight through Eleven
The Mark of the Beast Storyline, Chapters Twelve through Sixteen
The Fall of Babylon Storyline, Chapters Seventeen through Twenty-One
The four storylines in the Book of Revelation (BOR) provide for cross-referencing to gain a fuller picture of what the book is about. Each storyline has supporting chapters that I call asides. These asides present the emphasis for the storylines.
In the seals storyline, the aide and emphasis of the storyline is Chapter Seven.
In the trumpets storyline, the aside and emphasis of the storyline is Chapter Ten.
In the mark of the beast storyline, the aside and emphasis of the storyline is, part 1 Chapter Thirteen, and part 2 Chapter Fourteen.
In the fall of Babylon storyline, the aside and emphasis of the storyline is Chapter Twenty.
This information is for the followers of Jesus Christ.
By removing the asides, the storylines are as follows:
The seals storyline, Chapters Five, Six, and Eight (The Chapter Seven aside removed)
The trumpets storyline, Chapters Eight, Nine, and Eleven (The Chapter Ten aside removed)
The mark of the Beast storyline, Chapters Twelve, Fifteen and Sixteen (The Chapters Thirteen / Fourteen aside removed)
The fall of Babylon storyline, Chapters Seventeen, Eighteen, Nineteen, and Twenty-One (The Chapter Twenty aside removed.
Thus, the asides providing the emphasis for the storylines are Chapters Seven, Ten, Thirteen-Fourteen, and Twenty.
I hope that everyone will hear this information and draw their own conclusions.
Another interesting detail is that Chapter Eight ends the seals storyline and begins the trumpets storyline.
The reason is that there is a division between two periods of time being represented in the chapter.
That is, Chapter Eight has a midpoint included between the seals, as a period of time, and the trumpets as a period of time.
The seals, 1 through 7, are in Chapter Six as well as Verse 8:1. And the trumpets begin in Rev. 8:7 (v. 8:7-11:19). Thus, the verses between Rev. 8:1 and Rev. 8:7 are midpoint verses harmonizing with Chapter Fifteen in the mark of the beast storyline.
Therefore, in the mark of the beast storyline (Ch. 12-16), everything before Chapter Fifteen (Ch. 12-14) is in the time period of the seals storyline (Ch. 6-8). And the chapter (Ch. 16) that follows is in the trumpets storyline (Ch. 8-11). That is, a long version of the story is in Chapters Six through Eleven.
There are two things to keep in mind. The four storylines work together to tell the story, and secondly, a long version of the story is in the seals and trumpets combined.
