The elder I studied with came to my house a month or so back and told me he's been doing metropolitan witnessing in Birmingham. He said he was aproached by a guy who said he was an Atheist, this guy asked the elder why he believed in God. The elder replied: " Do you know why I belive in God? I belive in God because of Ikea. I bought my son a shelving unit from Ikea which came flat packed, I layed all the parts out on the floor ready to be assembled. Now if I'd have left all those parts on the floor for years they still would have been exactly as I left them. The unit couldn't of assembled it's self." He said the Athiest guy gave him a look like he actually got it, and then just walked off. The elder told me that he thought he'd really got through to that guy. I shit you not he really said all this.
I just sat there thinking the Athiest must have just been shocked at what he'd just heard, thought the elder was beyond help and so he walked off. This elder has been a JW for over 40 years, so as log as they have people with his skills out in public I'd say an increase in numbers is unlikely.
My mothers friend who is also a JW said she was doing the trolly work and a young ish guy approached them, but he didn't seem to want to talk. So, she asked if he needed any help, at which point he broke down in tears and told her that he was raised a JW but left "The Truth" a few years ago and kew Jehovah didn't love him anymore because he'd spoken ill of God org. Anyway, long story short she asked if he would like her to arrange for a brother to call on him for a study. At which point he cried even more and couldn't thank her enough for helping him. Now, to me this guy sounded like he possibly had some mental health issues and would have been much better off seeking help for that than getting wrapped up with the JW's again.
