For me the start of my waking up was my disfellowshipping in April of 2015. Since I had never been DF'd before I took it pretty hard and I was really struggling with some personal non-doctrinal related issues.
I still believed it was the truth for the most part and was contemplating getting my act together and getting back in. Then I decided to do some research on the organization and see what if anything was to be found out there on the internet. I found jwfacts.com and that was where the real eye opening happened.
Three things really clinched it for me.
First of all I should say this; I am now agnostic. I pretty much believe there was a creator or a first cause to all of <this> around us. To me that seems obvious and I think even science must somewhat agree with that idea that something had to cause it. Something doesn't come from nothing. Life does not arise spontaneously. But I digress....
The three lines of reasoning for me are as follows:
1. Deut. 18:21, 22
21 You may say to yourselves, “How can we know when a message has not been spoken by the Lord?” 22 If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken. That prophet has spoken presumptuously, so do not be alarmed.
The JW religion has made many many false prophecies over the years. This alone was enough for me to scratch my head and say "Yep, they are not the one true religion." However I don't believe in the Bible anymore anyway so....
2. The whole 1919 "Jesus examined us and chose us out of all other professed Christians at the time because of what we believed" etc... (quotes mine) Then when you look at just what the JW org was believing at that time there is no resemblance of what they believe now. They did all kinds of un-christian pagan things back then.
3. Finally, the ARC. When G. Jackson was asked if the org taught that they were the one true spokesman for God on Earth and he bold faced lied and said "Well that would be presumptuous of us to think that...." I about fell out of my chair. For a GB member to say that......it just blew my mind because this is precisely what they believe and teach. Theocratic warfare my ass.
I'm fully awake now. I have no fear of them at all.
