Things seem so obvious don't they from the outside looking in.
But I'm telling you, my JW friends don't THINK about this stuff. They don't want to even talk about 1914, or MY favorite subjects, "can the 'paradise' really work?" Most my friends don't read they magazines, they say "once is enough" at the WT study.
I find it interesting what was said about the de-emphasizing of the paradise and the focus on trusting the "slave". Ground work for sure for upcoming changes, tweaks, adjustments.
I don't think they will let go the paradise earth doctrine.
A few years ago when I was "in," a group of us were sitting around discussing much the same things that are discussed here. An elder joked about going to the door saying, "Good morning, I'm one of Jehovah's Witnesses and we don't know what we believe."
