at my church, they’re in the midst of a teaching series on doubts. in a nice attempt at creating a bit more of a communication loop, they invited people to text message questions during the sermon — questions about points that needed more clarification, or about related doubts and questions. at various points during the sermon, the teaching pastor stopped and some of the questions appeared on the screen, where he read them out loud and took a stab at responding to them. it brought greater clarity to some of the issues being addressed, and brought up some great ancillary discussion. for a large church, this worked way better than having an open mic where people could ask questions, as it was substantially quicker, and allowed for some pre-screening of the questions. it also allowed people to ask questions who would not normally make their way to a mic to ask something in front of a room of 1000 people.
