An incarnational mode creates a church that is a dynamic set of relationships, friendships, and acquaintances. It enhances and "flavors" the host community's living social fabric rather than disaffirming it. It thus creates a medium of living relationships through which the gospel can travel. It emphasizes the importance of a group of Christians infiltrating a community, like salt and light, to make those creative connections with people where God-talk and shared experience allow for real cross-cultural Christian mission to take place.
