I was telling the story of Abraham and Sarah waiting and hoping to have a baby. Somehow I managed to ask how long it takes to make a baby...which got some interesting answers (from both the children and the adults in the congregation). I also suggested that A & S were quite old, perhaps as old as the children's grannies and grandpas - only to be corrected by one child who informed me that her granny was very young and could easily have a baby...
All this reminded me of something I once said to O - that it would be a good idea to invite feedback from the congregation during sermons. I can understand now his reluctance to embrace this suggestion...
