Really nice posts on this one. The outcome for is that indeed hours do not represent the actual preaching.
And since WT is focusing on hours then the rank and file will go for hours. Not for God's message to the people. So focusing on wrong target it is the real issue.
On the other hand WT's "good news" have not reached to the ears of many people. Even in my country that the ratious is about 350 to 1. Now that I left I ask people(friends etc. etc) what do they know about JW's.
If they have a relative JW they could give you some tips, but most of them THEY DONT have a clue regarding JW's and what they preach.
All they will report the negative parts of the WT. Blood issue, military service, cross, christmas. So JW's are famous for all this, and not for their 'good news'.
