The document discusses forming missional communities and how change happens gradually through different stages of adoption. It provides rules for missional life based on Luke 10, including catechesis, going local, packing light, eating what is offered, and being open to the unpredictable work of God. Leadership is called to cultivate environments that release the missional imagination of a local church in relationship to its context. Change rarely happens directly but through gradual adoption as people become aware of, interested in, decide to try, and eventually adopt new approaches or ideas.
