I have noticed an apparently increasing number of men who are not interested in becoming Ministerial Servants or Elders. I also know of some that have voluntarily stepped down (which is my case) for no obvious solid reason.
I remember, during my teenage years or even during my twenties, the brothers were always looking forward to being appointed... Although many still do, I have noticed there are many others with whom you do not know what the deal is.
Since there is no freedom of speech within the organization, we remain in the dark about the motives and desires of everybody else. I attend a congregation with only two Ministerial Servants, while it is full of men who do not seem to be willing to do more.
It is hard to tell exactly what is going on, since honesty is not possible while you are inside, but I am starting to think that more and more are becoming disillusioned...
