Articles on the subject of Revelation and prophecy accrue many hits to Preacher’s Study. I’ve come across an article that you should read if this area interests you.
Wayne Jackson discusses both Revelation beasts and offers careful study to help understand them.
Jackson mentions a couple of books in his article. I would add Simon Kistemaker’s Exposition of the Book of Revelation as another well balanced view of this great book. Jesus gave the message of Revelation to John with the intent that John should write ot down and give it to us. Let us carefully study this great book.
