I've been a small group and discipleship pastor for nearly ten years now, and in that time I've seen lots of different theories and resources for how to develop discipleship systems. I've led the groups ministry for a large mega-church, for a small church plant, and I've listened to, coached and counseled churches of every size in between. In all my experience it is rare to find someone who's not just talking about a new process or program but a whole new paradigm on discipleship. This is what Mike Breen and the folks from 3DM are offering. These aren't just theories or abstract ideas; this is a book borne from the labor of leaders on the front lines working with one burning passion - to create growing disciples of Jesus Christ.
One caution: do not read this book as you might all the other small groups or discipleship resources out there. Do not go looking for the next "how to" book on creating a new program or system. You may even read this book and think, "So what. That seems too simple." But do not let the simplicity of the ideas obscure its power. Read the book, reflect on its ideas, and if you are stirred by the concepts presented, I suggest you find someone already implementing these ideas in their church and learn from them. You cannot put new wine in old wineskins, and you won't be able to apply many of the principles in this book without letting go of some of your existing paradigms. Seek out someone who can help you with that journey. We've greatly benefited from the learning of others who have walked this road ahead of us.
