Hello Desertrose!Thank you for your kind words, but the answer is no, I have not taught, as in a classroom setting, but only in fellowship with individuals face to face and on different forums, etc. The problem is that, we have people who have not put in the time of study who are attempting to teach on Revelation and end-time events. Many of them just repeat what they've heard or what they got off of YouTube, other websites and from the myriad of books that are out there.As far as comparing Revelation and OT prophesies, I always incorporate them when applicable, such as Daniel, which I consider a sister book to Revelation and all of the references in other scriptures regarding end-time events. For example, in order to understand who the woman of Rev.12 is, we have to go back to Genesis 37:9-10 to get the answer. Otherwise, any of the symbolism in Revelation is revealed right in Revelation itself.
