Substitute teaching can be a challenge in Jimmy Carter’s class

Every now and then, Sunday school teacher Kim Fuller makes a point during class and the old man sitting on the front pew raises his eyebrows quizzically.

That old man is her uncle, former President Jimmy Carter — and Fuller’s unique challenge is to serve as his substitute in the class he usually teaches himself.

Fuller is the eldest daughter of Carter’s late brother Billy Carter, and she has served as the regular replacement for the world’s best-known Sunday school teacher since Carter underwent brain surgery in November.
