"If you don't promote it you don't have to defend it."
I was counciled for watching R rated movies... I had mentioned Schindler's List out in service and someone in the car group ratted me out.
Another Elder who admitted to watching Rs told me the above...
It is really good advice and applies to more than you would think.
When asked why I'm currently inactive I used the above line of reasoning in reverse...
I can't defend (from the bible) new lite such as overlapping generations so how can I promote it?
The Elder admitted he didn't understand it either but he was "waiting on Jehovah."
"My sentiments exactly" I said, he gave me a weird look.
