If they really believed they had the truth, they would be eager to share it. This "experience" shows that the majority of J.W's today do NOT believe they have the truth.
When I was fully in, I would have engaged anybody, anywhere who posed that question to me. I was confident I could make a very good job of defending my faith. I had crossed swords with Vicars, Priests and one time a full blown ( no Pun intended LOL) Bishop !
Admittedly ,looking back, I know all those Seminary trained guys actually got the better of me, they won the debate !
But I was still never afraid to talk to anybody about my beliefs.
The Cognitive Dissonance of constantly hearing " the truth, the truth, the truth" and yet deep down knowing it is not, must be mental agony for today's JW's, who I think evidently are dishonest and have no integrity.
