Hello Dave713,
Revelation has yet to be fulfilled. God gave us the information in Revelation to show us the things that must soon take place. The majority of the book of Revelation is given to the wrath of God via the seals, trumpets and bowl judgments.
The chronological order of the book of Revelation is revealed in Rev.1:19 where John is told to write:
What you have seen = Everything written from Rev.1:1 to 1:19
What is now = Represented by the letters to the seven churches, which represents the entire church period
What will take place later = Everything that takes place after the "what is now" i.e after the church periodll
Currently, we are still in the "what is now" part of the program. Once the church is completed, the Lord will descend from heaven and the dead in Christ will resurrect and immediately after that, those in Christ who are still alive will be changed into their immortal and glorified bodies and will be caught up with them to meet the Lord in the air. At that time the Lord will take the entire church back to the Father's house in fulfillment of John 14:1-3 and 1 Thes.4:13-18.
After the church has been gathered, the the "what must take place after this" will ensue, which is the last seven years of the seventy seven year periods that were decreed upon Israel and Jerusalem (Dan.9:24-27). The "what must take place later" will be the pouring out of God's wrath via the seals, trumpets and bowl judgments.
We are and have been approaching the Lord's appearing and his gathering of the church. That is obvious because we are seeing the stage being set for many events that are to take place after the church is gone, such as the electronic crediting and debiting technology which the mark of the beast will run on. That coming mark will replace card swiping, cell phone bank apps and whatever else is being used to access one's bank account. During the time of the beast cash, checks, cards, bank apps and all other methods of buying and selling (crediting and debiting) will be made obsolete leaving only that mark.
The next event is the gathering of the church, followed by the "what must take place later."
