Dietrich Bonhoeffer, Life Together

I highly recommend this classic work on the importance of Christian community. Coming out of his experiences in the Confessing Church seminary in the years leading up to WWII, Bonhoeffer's spectacular book both outlines the theological foundation for a robust and intentional communal life, but also gives practical advice on how to bring it about. While we certainly won't all be participating in the daily type of community that Bonhoeffer envisions (though it is very different from a cloister life, in that it is intentionally pointed toward and among the world in service), his vision is filled with great wisdom and insight for appreciating and reinvigorating our participation in our churches and smaller fellowship groups today. Teaching about Bible reading, prayer, service, and confession, Bonhoeffer paints a picture of the Christian life that preserves one from self-absorption and brings one into the support and fellowship of the communion of saints as we encounter Christ in one another. Truly a must-read.
