Tomorrow I am teaching two sessions on missions at Praxis. The first will be a more practical and interactive look at Luke 10, some church planting movements overseas that are doing well, a few controversial issues related to that. For those that cannot be there, I recommend reading
11 Practices of a new Jesus movement (Lausanne)
The second session will deal with subcultures and what kinds of ministries have succeeded over the past few decades. Here's some material that I will be referencing.
Understanding subcultures (Underground Ministries Handbook)
