I'm so sorry for what you are going through. Hassan says as long as they are breathing there is hope. I have doubts too - my mom is so far gone.
On the 1914 issue my favorite point is that they had to change the masthead on the Awake magazine in 1995. Is your mom aware of that? From what I understand they did it quietly so some did not even notice. I'll try to find the quote for you -- but the changed "the creator's PROMISE." It just blows me away that JW's don't even care about that. Why call it a promise if its really just a typo?
Your mom at least listens a little....maybe you have planted a seed or two. Prayer though may be your best bet, IMO.
My best to you
I found the quotes:
Hope it helps
The Jan 8 1982 Awake is the first one to use the phrase ?the Creator?s promise of a peaceful and secure new order before the generation that saw the events of 1914 C.E. passes away.?
The November 8 1995 Awake is the first one to change the phrase to read ?the Creator?s promise of a peaceful and secure new world that is about to replace the present wicked, lawless system of things.?
