I often wonder how does the average JW get past the obvious words at Romans 12:1
"Present yourself...acceptable to god, with YOUR POWER OF REASON"
The very essence of being a witness is to SWITCH off your thinking reasoning, and just blindly follow the GB?
"listen, obey and be blessed"
Dont think or reason on anything, except if that reasoning is to nod in agreement to everything spewed forth...even if the teachings change in a few years time!
