Revelation 1:
[3]Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand.
I would just like to toss out a couple general remarks about the Book or the Revelation.
God meant for this book to be read. Not just once, but the word “readeth” has the meaning of being read over and over again.
God meant for this book to be heard, or understood. If God did not mean for this book to be understood then He would not have made understanding it a condition for being blessed.
God also meant for Christians to keep the things written in this book. Again, how can we keep the things in the book if we cannot understand the things that are in the book.
