HI! I've never been a JW, but I sure know a few!
Have you thought about getting some of the older WTS books/literature? Especially the ones that show what they used to teach? Like the Harp Of God, with the pictures of Jesus on the cross, the prediction of Abraham, Isaac and Jacob coming back in 1925, etc.... You can find them on ebay. Even the Proclaimer's book. Chapter 5--Russell preached (the Lord's truth, not his own) is that Jesus came back in 1874. He preached it all over as GOD's truth. If it was God's truth then, shouldn't it still be true NOW? Didn't God know when His own Son came back? I have aquired quite a collection. Show the folly in present publications as well. I asked my JW friend why the blood brochure she gave me said that white blood cells are forbidden, yet white blood cells are in breast milk! You mean JWs are not allowed to breast feed their babies?! I mean that is literally eating white blood cells! You mean if a guy is bleeding to death in the emergency room, and the doctor can't find any tubes and needles to give him a blood transfusion via his viens, he would tell the nurse to just put it in a glass and have the guy DRINK it? If it is the same thing, then why not? You will get lots of great info. from this website, I am sure.
Then there are many great books to give ideas of how to plant seeds. Captives of a Concept, Approaching Jehovah's Witnesses In Love by Wilbur Lingle, Rescuing Loved Ones From The Watchtower Society by David Reed (I think he was the author?). Lots of great books. Always use the Columbo approach. Ask questions, rather than point fingers. That seems to be easier for them to digest. Just don't get impatient or expect it to happen quickly. This is my 5th year of planting seeds, but my friend is still in the honeymoon phase. I think she will have to feel some pressure (negative) from her "friends" before she will entertain any serious doubts. I think you have to reach a point where you are disenchanted and longing for freedom. It makes investigating the WT less daunting. I have faith that it will happen. They can't keep up the BS forever.
Haven't been on the forum for a LONG time. Good to see so many familiar names are still posting. And lots of new ones. You will find a lot of support and friends here. Welcome!
