This book exposed 3 things that made me wake up...
1) The Watchtower has forcefully given itself credit for 2,520-year (7 Times of Gentiles) calculation when, in fact, this calculation was made at least 50 years before the Watchtower even existed. In the 2010 DVD Faith In Action, Anthony Morris even states "The fact that they (the Bible Students) were able to pinpoint that year is just phenomenal." What he doesn't mention is that John Aquila Brown was peddling this 7-Times calculation 50 years before the Watchtower was even founded and that several religions were looking at 1912, 1913, 1916, 1917, etc. as the year for Armageddon. The Bible Students chose October 1914 but then latched on to WWI (which started in July 1914) as proof that they were right. Right about what?
2) Jeremiah 25:11 unambiguously mentions 70 years of servitude. It also mentions the word "desolation" but DOES NOT say how long that desolation would last. However, the Watchtower has chosen to completely ignore the word SERVITUDE and substitutes it with the word desolation so that their false doctrine about 607-1914 will at least make some sense. They do this because they know that there was no servitude after 539 since Nabonidus and his son Belshezar were killed in that year. I hate to state the obvious, but that would mean 68 years of servitude (2 years short of 70).
3) The Watchtower has a long history of taking secular sources completely out of context to prove that they are right about this 2,520-year speculative calculation. They do this despite Jesus' reminder about speculating on things that are under God's jurisdiction (see Acts 1:7).
Jonsson hit the nail on the head with this book.
