Read page 234 in the Reasoning from the Scriptures book, under the heading of Last Days, where it reads:
"The present wicked system of things, which extends worldwide, entered it's last days in 1914, and some of the generation alive then will also be on hand to witness its complete end in the " great tribulation. "
to my understanding they still use this book.
The Reasoning book is still current, but that quote is now "old light", replaced several times over by newer publications. I'm surprised that they haven't reissued the book with "updates". It is silly how you can pick one current publication and it contradicts another...
And how is it that the Bible, the supposed basis for all these teachings, hasn't changed in hundreds of years yet the WTS publications (spirit directed, mind you) have a shelf life of about two decades...at most?
