This book gives a great overview and Biblical grounding for being missional. For those who are new to this concept of living missionally I encourage you to pick this book up and read it. Phil Strout has a great way of comunicating Biblical principles intermixed with his own stories. I loved how he grounded all missions in the local church, and showed that Paul operated in that way as well. I would recommend that 90% of American Christians read this book, here is a great quote from Phil:
God is the hero of this story-not people, not churches, not missionaries, not mission agencies. Since the beginning of time, God has been the one involved in making this mission a reality, not us. As God wins each of our hearts back and we discover the portion of community and intimacy that He has for us today, we become His people. However, when we become His people, we are invited to participate in His mission, His pursuit of the hearts of humanity. When God grips our hearts with His love and compassion, it is unavoidable-and we, too, become missional people.
