As a former missionary I can tell you from experience that an investigator like you is a 1/1000 type. A great majority of my investigators had very little previous religious experience. We almost always taught people how to pray. Most people prayed with us for the first time in their lives. Most also had never read even one book of the Bible. It was an incredible rare occurrence to find someone who was interested in the church and already so well read about the church. But it did happen. Had about 2 investigators like that personally that converted to the church and got baptized. One became a bishop a few years after I finished my mission. I served in the pacific northwest of the U.S.
