I recently finished the booklet A Radical Idea by David Platt. Platt is the pastor of a church in Alabama, as well as the author of Radical and Radical Together, both of which have been bestsellers and have had a profound on the way that many do church in America.
The booklet A Radical Idea is a short consolidation of the ideas that were presented in Radical and Radical Together. Platt is seeking to convict individuals of the way that most view the church. Instead of viewing church as a gathering of individuals who are equipped to serve and minister to others, many view the church as an opportunity to be ministered to and to bring their friends so that they can be served by the professionals who run the church. Platt wants to turn this idea on its head. His desire, using Scripture as his basis is to have the pastors equip the people of the church to mobilize and serve those around them, sharing the Gospel as they go.
Most, if not all, of the material presented in this short booklet was culled from his previous two books. As such, if you have read Radical or Radical Together, very little of what is presented here will be new or groundbreaking. These booklets are, however, an excellent introduction to the writings and ideas of Platt. It is my belief that they would serve great for a discussion group or a discipleship program. I would suggest them, but not in place of the full discussion provided in the full texts.
