For me it was reading the 1927 edition of the "Creation" book by the IBSA, where it tells us that clearly the Bible shows that the last days started in 1799, the Kingdom was est in 1874 and Christ was given rulership of that Kingdom in 1878. Also the "Study of the Scriptures" 1910 edition contained these same dates. How could that be since today we are told by WT that all these events took place in 1914 and that WT had been saying 1914 for almost 40 years before 1914. This was back in 2002 where I raised this issue with another JW who basically accused me of reading apostate books, that floored me and left me speechless on the spot. How could WT lie so brazenly about their past? That starting the cracking of the WT protective shell for me, made me wonder, what if these wicked apostates were also saying this very thing. Finally, with my heart almost pounding out of my chest, looking all around making sure no body was watching, I went to the (what was then) wicked internet for an answer. Sure enough, apostates were telling the truth on this subject, how could that be since according to WT, apostates are the ones that make up lies? Then the flood gates opened on WT.
