The Book of Revelation also contains many time indicators.
“The Revelation of Jesus Christ, which God gave Him to show His servants--things which must shortly take place. And He sent and signified it by His angel to His servant John” (Revelation 1:1).
The content of the book of Revelation was going to take place shortly.
“Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near” (Revelation 1:3).
The time of the fulfillment of this prophecy was near, not an indefinite period of time away.
“Then he said to me, “These words are faithful and true.” And the Lord God of the holy prophets sent His angel to show His servants the things which must shortly take place” (Revelation 22:6).
At the end of the book, God confirms that these things will take place shortly.
“Behold, I am coming quickly! Blessed is he who keeps the words of the prophecy of this book” (Revelation 22:7).
Jesus also states that he is coming quickly. All of these time texts point toward a more immediate fulfillment of these prophecies.
Thus, Preterists hold that the book of Revelation was fulfilled in the first century.
This might seem difficult to understand at first because this means that the seals, the trumpets, the bowls, the beast, the false prophet, the binding of Satan, etc., took place in the first century.
However, if we take the time texts seriously, we will find that there are good and reasonable explanations for these prophetic details.
