The 7 trumpets in Revelation and the explanation given in the : book of "Revelation Its Grand Climax" or some such title that it depicted the Conventions that started In Cedar Point Ohio ? in 1922 ,then the following six more Conventions each year thereafter .
I thought that was a bit much ,maybe it was another nail in the coffin as regards my belief in JW religion.
At the time it was written I thought the green book "Yout Will Be Done" was a really good study book,dealing with the king of the North which was then USSR that now doesn`t exist { Union of Soviet Socialist Republic } and the so called Anglo-American World Power,that never really existed anyway looking back now.
But at that time it did seem to make a lot of sense during the "Cold War"
