I've run into Mormons in service - and I'd cringe everytime. They could talk circles around me and they and I knew it.
I've never understood their religion - at all. However, in several books on cults, Mormons are listed right in there with Jehovah's Witnesses. Hope your study goes well.
There really is a great feeling studying the Bible, and actually discussing it. Makes you work hard, doesn't it. I hope so, because I had one like that - and prepared harder for that study than any meeting. The study did not come into the organization - but I really enjoyed my time with that woman - she made me think.
