What are you reading? If you are leading the small groups in your church, what is informing your leadership? I know that you have the normal stock of books on group leadership, training manuals and plenty of stuff on small group strategies. And of course everyone has Life Together by Bonhoeffer.
Let me also encourage you to add these to your shelf or electronic devise. These are not the normal how-to books. Instead these are books meant to equip your soul and challenge the way you see groups and community. Admittedly, these authors are not writing about Christian small groups. In fact, only one of them would be labeled as a "Christian" author. But these books can point us in some new and prophetic directions.
A Different Drum by M. Scott Peck
Community by Peter Block
A Hidden Wholeness by Palmer Parker
Christ Plays in Ten Thousand Places by Eugene Peterson
Community by Zygmunt Bauman
These are books that have influenced my writing in Missional Small Groups and MissioRelate and they continue to challenge me.
What books about groups and community are challenging you to think differently about how we live in community with one another?
