I personally think the truth which the JWS are missing all together is that the WTS has devised and constructed a doctrinal Gospel (1914) specifically to assist toward the proliferation of the literature of which this organization publishes itself.
They allure people with them then exploit these ones further in the distribution of those pieces of literature all while stamping the information as bible truths.
I see JWS as well controlled robotic sales representatives for this unscrupulous religious publishing house.
The causative result is that they think they are pleasing Jehovah and in turn they will be rewarded by him for their steadfast devotion.
Only problem is the Gospel which the WTS preaches is not an parallel accurate one according to the words of Jesus himself, it is false and commercially tainted . Most of this observation goes over the heads of devoted JWS.
I was in a Starbucks yesterday and four JWS who I guess were out in service sat right next to me and I couldn't help notice how many times the phrase is she in the truth or they aren't in the truth repetitively. I was tempted to interject but I didn't I just smiled at them and left.
Being out of religion for more than 30 years I cant help be dismayed that people today in this age of information are still believing in ancient mythology, words and activities expressed by forgiven ignorant humans, 2 to 3 thousand years ago.
