Preaching as dialog

More and more today people are prepared to question authority. No longer do doctors have such a privileged position as a purveyor of information regarding medicine; people are likely to check out their condition on the Internet, consult alternative treatments or consult second or third opinions. The role of minister is also changing; no longer are ministers the sole source of religious truth.
The idea of preaching becoming more akin to dialog is necessary. In my role working with children's ministry I see first hand the desire to ask questions and to discuss the lessons. When the young people each 13 we send them off to youth group where they are in an environment that supports query based learning, where discussion is extolled and all peoples opinions are considered valuable. What happens after youth group is they are expected to sit in a church sermon, listen to a preacher for twenty minutes, sing a song of reflection or listen to a prayer, and then go about their day. By providing dialog as a form of preaching we enter into communication a 'two way street' which allows peoples personal life to enrich the message and help others to relate to the message, and one would hope apply some new truth to their lives. In encouraging dialog the preacher is opening themselves to become vulnerable, which is threatening and removes a sense of the power imbalance and distance between a preacher and congregation.
