OTWO nailed it in my opinion. Late in the night last night, my daughter and niece woke us up. While we were trying to get them back to sleep, my wife sung a song from the song book that she knew by heart. After she finished and before she could start another song, I asked her, "What if your beliefs are wrong? What if 1914 really is not the date the WT makes it out to be? You rail against christians for celebrating Christ's first coming on December 25 yet excuse the WT for proclaiming his second coming in 1914. If that date turns out to be false, how are you any different from Christians who still believe 12-25 is His birthday? At least I, thanks largely to JW's, know that it is not. Would you be willing to consider that 1914 could also be wrong?"
She then went on about new light and how of all teachings this one (1914) hasn't changed. Therefore, there must be something to it and we must believe that Jehovah will reveal it. Still looking for a way out, she is trying so desperately to find a way out, it is really sad.
