A couple of quotes from Michael Frost's Exiles...
We cannot demonstrate Christlikeness at a distance from those whom we feel called to serve. We need to get close enough to people that our lives rub up against their lives, and that they see the incarnated Christ in our values, beliefs, and practices as expressed in cultural formes that make sense and convey impact. (p 55)
I would argue that in today's society, any attempt to model your life on the life of Christ must include a genuine attempt to hang out regularly in third places. Genuine incarnational living demands it. Missional proximity can best be developed in bars, pubs, gyms, grocery stores, beauty parlors, community groups, and coffee shops. (p 59)
