One good way to get your mind around the New Testament Book of Revelation is to understand the relationship between the 7 seals, 7 trumpets and 7 bowls of wrath.
First of all, “7” is the number of completion, perfection. And so what we have in the 7 seals, trumpets and bowls (imho) is the completion of the age-long judgments against a world that refuses God and the removal of the evil that has it bound. (The Dispensational / Futurist method of interpreting Revelation would have all these happening after the Rapture. I propose that only God’s wrath does.)
Which brings us to what I have come to refer to as the “waterfall” outline of the Book of Revelation (see below). It starts out with the 7 seals.
And then I want you to notice the 7th seal which equals the 7 trumpets. Another way of putting it: The 7 trumpets are contained within the 7th seal.
Lastly, there is the 7th trumpet (which is just such a moment in the history of mankind). Of course, the 7th trumpet is the “last trump” of 1 Thessalonians 4:16-18. It is at the 7th trumpet that the rapture of the Church takes place. And just as the 7th seal contained the 7 trumpets, among other things the 7th trumpet is equal to / contained within it are the 7 bowls of wrath, too.
(Note: The 3 “woes” equal the 5th, 6th and 7th trumpets. respectively. The “trumpets” encompass and give an overview of the release of the demonic in judgment upon wicked men. Could it be Satan himself who is the 3rd woe? I think so.)
I hope this “waterfall” outline is helpful to you in your understanding of the Book of Revelation…
