Contemporary Christian Fiction discussion

I have a question for those in book clubs.I would like to create a set of questions for my novel, but I'm not sure what direction to take them. So far, I've got a short list of questions related to the spiritual thread in the story, but I would like to add some about the characters, setting, and plot as well. What type of questions does your book club like to discuss? Are they general questions about what you liked/disliked or do you discuss specific questions about things that happen in the story? Thank you for any and all input!
