It's Sis Wasblind,
1) On page 14 in the reasoning book it states that humans live just 70 or 80 years then die. In this same book they specify that the generation of 1914 is now well along in years, and time remaining is very short. According to this book the big A is already past due.
2) Dueteronomy 18:21-22 does not allow correction for any given prophecy, there is no indication in the Bible that show a prophet was allowed this.
3) It does not matter if they issue a new book to replace the reasoning book, The change will only reenforce the fact that what they taught previously was wrong. And there are to many of these books out there to prove what they had written, they could never recover them all even if they tried
4) Because they taught this as a fact, world wide, In the Name of Jehovah and it didn't come true makes them false prophets.
