This organization is all about numbers and titles. It has been from it's "humble" beginnings - around 1919, 2nd president of the Society - J.F. Rutherford - began to require weekly time reports from the "publishers." It's why we have a yearbook and experiences at the assemblies.
It would seem that if all of the JW's really believed that Armageddon is going to happen any day now, we would be going crazy warning everyone all of the time! It's "lip service" that most commit to doing - meet for field service, make a call, break for coffee, work a street or two, hit a yard sale, make a quick return visit, meet back at the hall, smile and compliment each other, share an experience, take off the tie before leaving the parking lot, get out of the suit/dress asap.
Duty done!
