I agree 100% COMF. I won't attribute the change in me (after 4 decades of being a true believer in the WTS being the ONLY true religion) to just reading the "Crisis" book, but it sure was a significant turning point for me.
I had many things nagging away at me for years but always shrugged them off as my own weakness, lack of faith and study, or selfishness in not enjoying time in the service.
When I started to have some serious doubts stemming from not being able to agree on the benefits of rejection of family members or of any who were mistreated who were df'd or da'd but I won't go into a lot of detail here.
Anyway....as I said the "Crisis" book was a definite turning point for me. I had NO knowledge (like you said), and as I'm sure most of the general JW members, of the inner workings of the GB, the inner squabbles, the 2/3rd majority vote nonsense, or of the lies and coverups, the witch hunts,the double standards for countries, the deliberate mistranslation of some scriptures, the coverup of the 607 lie, etc. etc.
All these things were a completely opposite picture I had been given of a GB who is directed in all decisions by God's holy spirit and were only dispensing love and concern and knowledge for us poor, floundering sheep.
Reading the book was actually very difficult for me because of the lack of knowledge I just mentioned. I remember reading a chapter and having to get up and pace, cry, going back to read more, get up and pace and cry more. My whole foundation I had based my entire life on, just crumbled away and I just felt empty.
Tha foundation, the whole basis for my faith, had been grounded on the Gentile Times prophecy bringing us to the 1914 date of the last days and armageddon to come within that generation. It had been pounded into me at a ripe age and as the W81 said, belief in that teaching was essential to all JWs. So I did and felt so proud we understood its meaning.
With these and all the others things opening my eyes, I feel a great gratitude for having all of it brought out in the open in such a logical, informative, caring,non-judgemental way.
I too would recommend reading it for the sake of finding out all the details of all that has been hidden from us for so long.
Had Enough
