A wise guy on here posted a saying by another wise guy "When the student is ready the teacher will arrive" I beleive that sometimes the student is never going to be ready,but I also believe in gently giving them ONE question,such as
"Using just the bible can you prove to me that Jesus chose the Bible Students in 1919?"
"Can you prove to me that the WT is God's Channel from the Bible?"
"Can you show me from the Bible that the FDS is the Mediator?"
If they are willing to discuss one such question in a proper manner then maybe they are a student who is ready,if not don't waste your time, I know it stings when they think they are so right and we know they are not,but who is wasting their life?
