Is Revelation (Rv) in Order?

Here's a look at how the book of Revelation plays out sequentially...
Rv 1 thru 5: An Introduction:

Rv 1: Introduces us to "The Revelation of Jesus Christ", and then presents us with an overview.

Rv 2 & 3: Is about 'The Church'.

Rv 4: Is about 'God's Throne' being set.

Rv 5: Is about 'The Scroll' that requires a person of unmatched Holiness to open. This person would have to be morally perfect, the complete opposite of sin, which had introduced death and total desolation. This person would have to have been born and lived His life on this earth without ever sinning once. Philippians 2:5-11. Someone who had fulfilled the keeping of the Holy Commandments as required by God's law Matthew 5:17-20. He would be Worthy to bring an end to the reign of evil, the 'Mystery Babylon' system, and "the man of sin". His Victory would show the triumph, and the power of Righteousness over Evil for a mortal man. (Only the Righteous God who became man could do this. His Name is Jesus!)

In Summary: These first five chapters are an overall introduction and consequently have an ordering of their own.

Rv 4 & 5: 'Introduce the Seals'.
Rv 6 thru 16: 'The Seven Seals':
 Scripture has clearly defined the Seals numerically. These chapters are “all” in order. The order is mathematically embedded via the numerical sequencing of Seven Seals. Within the seventh Seal are seven
Trumpets. Likewise in the seventh Trumpet are 7 Bowls.
{With this ordering in mind, Rv 12 &13's “content” seems to have deviated from the norm. Its two “Signs” Two “seeds”.  Represent the conflict of 'Good' over 'Evil'. The struggle between 'Light' & ''Darkness', and are in order, but there content took on a distinctively different form.} 
These “Signs” represent a 'Selah', historical event that takes us all the way back to “Sins” first beginning in what once was a Garden of 'Perfect Innocence'. There it was in Genesis 3:15 that God had pronounced Judgment on mans first sin...  Since then this yeast (“Sin”), had spread through the whole batch of dough. It became a battle between the “Beasts Kingdom” and “God's Kingdom”, and apart from the work of the “Cross”, “Sin” has now reached its 'Final Hour'. The battle was won at the “Cross”, but God has tarried so that all who would believe in
the work of His Son Jesus Christ could be saved. Man-kinds cry for “Peace” is about to be realized at long last, not by their effort, but by God the Father's “Prince” of “Peace”, our Lord and Saviour!}  
(Seal 1 was a lie, and all the lies previous will bring mankind face to face with the 'Father of Lies' in the fourth Seal.  This Seal 4 is actually the first woe as described in Rv 12:12.  The internal content of Rv 12 & 13 wind up being extra information for the understanding of Revelation when used in context with scripture. Be a Berean. Know His Word, pray and use the Bible as your benchmark.

 - Rv 12 had begun with a “Great Sign” in heaven: It represents the Jewish nation getting ready to give birth to the Saviour of the world. The "2nd Sign" reflects the battle begun for the life and souls of God's
people and for the 'Title Deed' of the earth. It is the "Great Battle of Good Seed versus Evil Seed". This chapter is an ordered pageant from distant past, till evils end. It has useful information that overlays, key places within the Seven Seals and beyond.

- In Rv 13 we see the unholy Trinity of personified evil.  - These two chapters are added information (Inserts), and have their own internal unique ordering that is separate from the Seals.

Rv 17 thru 20:3: Epilogue's (Addendum):
This is simply added information (An Insert) about what has already taken place that applies to Rv16 and before. We see in these verses the Saviour and His Glorious work accomplished, Mystery Babylon
destroyed, Satan vanquished for 1000 years, His Bride safe and with Him, and the battle over evil Won!

Rv 20:4 thru Rv 22 Epilogue's (Conclusion):
These chapters are in order and pickup after "Rv16's "Addendum’s",  
(Rv 17 through Rv 20:3). "
