Certainly their heart does not seem to be in it - i.e their door to door ministry - anymore.
I see this with nearly all the ones that have called at my place over the last five or so years, anyway. They go about their business in the most perfunctory of manner, radiating the aura that they are there only so that they can enter a few "hours" on their Field Service Report for the month, and thus not feel too guilty about things.
Then, if they do meet somebody at the doors who even hints at being perhaps a little too hot to handle, they (the JWs) seem all too happy to have an excuse for disengaging the enemy and fleeing the field!
And, yeah, all along with a facial expression that communicates everything but being happy about what they are doing.
I cannot but contrast this with the spirit of most JWs 40+ years ago, who relished the thought of getting into a verbal sparring session with others.
My observations, anyway!
Bill.
