God has a Sense of Humor:)
When I was in seminary, our Christian Education class included the requirement to actually teach a class. If you chose to teach adults, your classmates would serve as the students. If you chose to teach young children, you would teach to an imaginary class. I chose the later option. I remember putting paper bags around the room with a name and a "self-drawn" picture of each student. We had carpet time, story time and a chance to sing. Awkward, but fun. Who ever thought it would be the perfect preparation for preaching in an empty sanctuary? God has a sense of humor!
