As an elder I was on the receiving end of the bitter disappointment, by brothers who thought they should be elder but were passed over.
One young man was very aggressive to become an elder. He was hardly dry from being baptized when he started partaking as an annointed. We appointed as an MS. Within months he let it be known he expected to be an elder. His naked ambition was the main reason we passed over him. He was pissed.
His ambitious nature later made him very rich and famous. As far as I know he is still a witness, and I'm not!
