It's mainly a numbers game and the organzation is losing at it big time. They have been dumbing down the message for years to make general recruitment easier and they have lowered the servant/elder standards so that basically if your willing to serve and you haven't been in any trouble in the past year or so you "qualify." Believe me, the qualifications of most now serving is laughable. I recently had a conversation after the bkstudy with a newly appointed ministerial servant (baptized for 6 years and very involved with the cong.) about the "faithful & discreet slave class". He thought that the entire class (all of the anointed individuals) were up in Brooklyn printing and writing all the "spiritual food" for us. I am not kidding. He was floored when I explained that while some annointed were involved in this, most were scattered throughout the earth in various congs. and had nothing to do with what comes out of Brooklyn (or Walkill/Patterson). It's sad in a way, but this is how low the standards have become.
Sure, in certain areas there may be enough bodies to fill the needed positions, but increasingly finding even these is difficult. The cong. I am currently associated with (approx. 114 pubs) has no less than 19 former elders/servants who attend, but do little in the cong. and want nothing to do with serving. Most only stay because the cost of leaving is too high.
