What always got me was their use of the term 'heart condition.' For example: "We need to be mindful of our heart condition towards Jehovah." Really?? Sounds like someone should call an ambulance!
I'd always found it to mean some kind of heart related medical problem, NOT a reference to 'where the heart lies' emotionally. At first, I thought it was just the way this elder talked...but then I heard it from other people, when I visited my wife's KH. Maybe it's in print like this too, I dunno.
Also...'worldly.' To me, it had always meant someone who is well traveled, or informed about the world. Visit JW-land and it has a WHOLE new meaning.
