Matt 6:2 Therefore when you do merciful deeds, don't sound a trumpet before yourself, as the hypocrites do in the synagogues and in the streets, that they may get glory from men. Most certainly I tell you, they have received their reward.
Ones "service" to Jehovah is meant to be done out of love for him and love for ones fellowman. Listing a speakers JW related accomplishments before he gives a talk is a way of boosting his personal credibility and a way of humbling the audience so they will be impressed enough to listen obey and be blessed.
I heard one such (late 50ish )brother give a talk where all of his Watchtower related accomplishments were listed before he got on stage. (Circuit Work, Pioneer, Gilead, etc) He proceeded to give a very authoritative talk that was peppered with disdainful comments about the world and its so called accomplishments.
The very next week I saw him wearing a hair net and and apron, handing out cheese samples at Costco. Not that there's anything wrong with that but It was ironic to go from seeing him in a $500.00 suit being lauded by thousands and making scathing remarks about everything and anyone non JW to handing out bits of cheese to cart pushing shoppers.
Since leaving the Circuit Work for health reasons, he and his wife/are
were living in the apartment attached to our Kingdom Hall and the
congregation pays for their utilities in exchange for special talks once
in awhile on Sunday. One part of me felt sorry for him and the other part was annoyed at his arrogance and condemnation toward those in the world. After all....what is he really doing...what is he really accomplishing himself to be able to condemn all those who actually are helping people in a real way in the here and now.
