I’ve been reading Breaking the Missional Code: Your Church Can Become a Missionary in Your Community by Ed Stetzer & David Putnam. What has impressed me about Ed (I don’t know David but I have had the chance to meet Ed a few times) is his loose grasp on the methods and his (and the books) emphasis on the principles. So whether you are an ’emerging church’, modern church, traditional church, historical church, mega church, house church or anything in between, this book is a valuable read to assess the missional nature of your own community and begin to look at your context as a place of mission.
Breaking the Missional Code isn’t a secret ‘grow a big church through techniques’ but a thorough and practical look at people & places, who through loving people and faithfully preaching the gospel, have had a chance to see lives changed. Yet, it does offer looks at ways churches are using new methods to reach a new generation of people as well as best practices of leaders who have succeeded in ‘breaking the code’.
I’d encourage you to read Joe Thorn’s review of Breaking the Missional Code (and he links to a few other reviews as well).
