My dad hasn't been to seminary. He has no formal theological training. Nobody pays him and Mom for their endless hours serving the church. But they could write an article on sacrificial service to the church. They've lived it.
Pop is a dentist in Spartanburg, South Carolina. He and Mom moved to town in the late seventies after dental school and a couple years practicing on marines. They didn't know anyone when they arrived. They visited churches, soon found one, and have been there for over three decades now.
