Dan Kimball in "The Emerging Church" (Zondervan, 2003) describes the missional church "as a body of people sent on a mission who gather in community for worship, encouragement, and teaching from the Word that supplements what they are feeding themselves throughout the week."
How about that for a paradigm shift? Just ponder Kimball's definition for five minutes. You may disagree with it, but it is thought provoking nonetheless. Are you on a mission? Why do you gather?
