If it is THAT serious, lets send out the heavyweights, lets train them right, and lets get the warning work done. The main reason though is to give the flock something to do. Keep em busy and distracted from all else that is wrong with this cult.
That reminds me of what someone said here recently about a CO saying that the different tract work campaigns was to "upbuild the brothers". It obviously was busy work, something to do for a change instead of the same old routine.
AllTimeJeff also mentioned the silliness of the WTS idea of people being approved by God based on their accepting two magazines. Some "good news" huh? How many dubs do you know that go to the doors and just present the magazines by saying...."hello, we are in your neighborhood offering the Watchtower and Awake...blah, blah, blah, blah, blah..." When they are done, the householder is left just thinking that a person was out passing out good reading material. That isn't how I recall things happening in the first century according to the Bible. They were very clear as to what their message was and what a person should do, which was to accept Jesus Christ and repent of their sins.
The more I think about it, the more I realize how off the WTS is.
