Cold Steel - I really don't want to take the Bible Lessons. I'm just interested in an occasional answer to a question by someone who knows what they're talking about and can add some discussion.
You can call your local Kingdom Hall and ask for a knowledgeable person to visit, be upfront and tell them what you are looking for. They might be prepared to visit once or twice, it depends how you handle it. You can tell them that you don't want to study their publications, you're just interested in researching straight from the bible.
You could also write to Bethel with your questions, they will likely pass on your queries to the local congregation for them to deal with.
