The door-to-door ministry, keeps the dubs busy, they always say see at Matt. 28: 19,20 blah blah blah but they never read it in context. Jesus was telling this to the 11 apostles, not every tom dick, harriet etc. that were his followers. That is why they had special powers ala Benny Hinn (yeah right) Their inflated opinion of themselves is nauseating at best.
The WTBTS use this to make $$$, you donate for the "free" magazines, and by god if you get a donation for them, they want that too. Like most things in business and politics it's follow the money. Most in the door to door work, don't realize they are being used period. It's a publishing company and if you aren't out in the "field ministry" and having to do so, then you won't be using as many mags as needed to keep the pub company in business. The more door to door workers donating for magazines makes money for the WTBTS publishing corp. It has always been a money maker for them, and thus they will never end it for a more logical way to get the word out.
The first century christians used the only means they had at their disposal for getting the word out, Radio, Tv, the internet etc didn't exist. What were they suppose to do paint scriptures on Camels asses as they crossed the desert in Caravans. Paint on animals sides and asses to get the word out. Would have been a lot of pissed off shephers, caravaners, farmers etc. if their animals had been painted. And lets not forget that most people of the word at that time just like the apostles with the exception of Paul were illiterate unable to either write or read, and that is directly contrary to the the pics put out by the society showing them carrying around paprus scrolls like they were supposedly reading the bible.
follow the money folks, that's why the d=t=d exists.
