Raised in the "Truth" I moved out of the home at 18. Moved 1000 miles from Oregon to Los Angeles. My parents helped me move, and got me settled in an apartment, got me all set up, and of course found a Kingdumb Hall for me. As an 18-year old 1000 miles away, the last thing I wanted to do was go to the Hall. Although, I probably still believed it was the "Truth."
I had some neighbors that were moving out of my apartment building, and since I didn't have much stuff, they told me to look around and I could take any furniture, stuff they were not taking. Well, I found an old book, Kingdom of the Cults by Walter Martin. I flipped through it and found a section on JW's. Interestingly, it was the only section in the book that had been underlined. I starting reading it and couldn't believe what I had found.
That was it, I read about all the false prophecies, failed dates, 1874, 1914, 1925 - and I was 10 in 1975, so remember thinking the "end" was going to come before I could drive. LOL. Anyway, the failed dates, false prophecies and the scripture in Deuteronomy that describes a false prophet "if what they say does not come to pass...do not be afraid of them." That was the moment - and luckily I escaped baptism :-)
