This is a textbook of sorts on a detailed commentary on line by line of the Book of Revelation. I read it many years ago for a course I was taking in Bible school. Before reading it, I didn't have a clue about the meaning of the Book of Revelation except there were several horses that would come on the earth and angels pouring out vials of tribulation. I didn't understand the symbolism or anything else. This book helped me tremendously. It also helped me to embrace the Book of Revelation as a loving warning from God of things in the end of times. I highly recommend it.
