At age 18, I was a Regular Pioneer. At 20, a Ministerial Servant. At 24 an elder. At 30, I was the Presiding Overseer.
In my old congregation you wouldn't have been considered for being an Min Servant until were round 30, never mind being PO.
I was 35 before I was a Min Servant and had been a JW for 15 years.
I was Literature Servant for the next 10 years.
Then through circumstances that led me to learn the "truth" about the Watchtower and DA'ing.
When they got my letter an Elder called me to say that they were going to recommend me as an Elder at the next CO's visit and could I not reconsider not DA'ing.
I had written that I could no longer continue as a JW becuase of learning about the lies and deceit of the Watchtower, and having read "Crisis of Conscience"
Yet here they were ringing asking me up to continue AND become an Elder !!!!
