In March of 2014, I was a very active JW, a ministerial servant, gave a public talk, was an attendant for the memorial, and one of 4 cleaning captains for an international convention of 40,000+ attendees. So what woke me up?
An innocent comment from a co-worker about the Candice Conti court case rang a bell that could not be unrung. This led to the silent lambs website, which led to me discovering that 3 brothers in my circuit were registered sex offenders.
After verifying as much as I could about the Conti case and the systemic problem of not reporting abuse to authorities and the 2 witness rule, I discovered many financial crimes/scams on part of the WTBTS, such as the Menlo Park scandal.
Then I found out about the 10 year membership with the UN as an NGO. I took a whole week off of work to call the UN, verify the allegations and make sure if there was any falsification to the allegations. I could find none. I was trying to prove the WTBTS true, but it was too easy to prove them liars. I was mentally done at that point.
I began trying to prove true everything that I ever believed, JW doctrine. Without WT lenses, I could easily see that what I had been teaching was utter nonsense, if not false - such as 607.
This led me to reading many of WTBTS's old, books from CTR and JFR days. I could not believe what I was reading! WOW! Pure ridiculousness!
But the straw that broke the camels back was researching in the WT's involvement in spiritism and its ties to freemasonry in the early days. When I discovered about WTBTS using Johannes Greber in support of their teachings, it made me want to run away from the religion I spent my life slaving for.
From March to July 2014, I went from a ministerial servant in training to be an elder, to full blown apostate.
I can't say there was one thing in particular that woke me up aside from the innocent comment from a co-worker, but it was a mountain of evidence that really did it.
How 'bout you?
