Alan Hirsch's book, The Forgotten Ways, is causing me to ask a lot of good questions of my theology, my ecclesiology & missiology. It's good, challenging stuff and I recommend you pick it up. I've been meaning to read/review this book for some time and it has been too long in coming. Over the next few weeks or so I'm going to make the effort to post a few quotes, reflections, and/or questions about the book and the issues it raises. Please feel free to interact with the ideas.
I wish I had time to do the book more justice, but Scot McKnight (for one) spent a good deal of time on the book (Part 1, 2, 3, 4, 5, 6, 7, 8). You might also want to check out Jordan Cooper's epic first half review here. I encourage you to go to these links for a good recap of the arguments of the book.
If the heart of discipleship is to become like Jesus, then it seems to me that a missional reading of this text requires that we see Jesus's strategy is to get a while lot of little versions of him infiltrating every nook and cranny of society by reproducing himself in and through his people in every place throughout the world.
