I think the term "heresy" is most unfortunate in a discussion forum. It conjures up in my mind the Spanish Inquisition and the burning of English Protestants in the reign of Bloody Mary. I have no problem with Preterism, save that I do not believe it to be correct, and certainly no problems with the dear folk who are Preterists. Hyper-Preterism is another matter.
Rather than Terry's book, I recommend William Hendriksen's More than Conquerors, first published way back in 1939, currently by Baker Book House. I read it as a new Christian who was hearing Premillennial interpretations which I could not believe, but was unable to refute.
Hendriksen's book is not a commentary as such - it is quite a small book, and it sets out the structure of Revelation in a way that a relative neophyte like me could understand.
If anyone is looking for a detailed commentary that follows Hendriksen's structure, I recommend that of Simon Kistemaker, also published by Baker.
