I wish he did, if I was your friend I would have done it.
I would have entitled the talk, "Make The Truth Your Own".
It would have focused on the boreans and how they did not just accept anything just because they were told it. How even though commendable many accept what they are taught without question, I would have then read from the "submission to God" brochure, made for muslims, about how those raised in a religion, etc, get no credit with God if they never critically look into the religion.
I'd of asked rhetorical questions on 1. Can you explain where 1914 came from? Have you researched it?
2. WHY is the FDS the only ones who can get holy spirit? If somebody asks, can they show how that started, the scriptures, etc.
3. If asking those in field service to investigate their religion, have they done the same? Can't be hypocritical.
Hopefully those who payed attention would have thought perhaps they should look all of that up so that they are firm in their beliefs and not asking those they approach in service to do what they themselves have never done.
