First, let me say that there were some good nuggets in this book. I was challenged by the idea of intentionally engaging with people at church within a ten-foot radius - it's been very helpful over the last few weeks for me to reach outside of my usual post-church group and talk to people I don't know.
That said, this book is far more helpful for someone in charge of an official church ministry than a lay member, which isn't clear from the title or back of the book. It also sets up being "outwardly focused" against other important aspects of the church, including nurturing the body of members. In one example, they shared a decision to remove obituaries from the bulletin because it made unchurched visitors uncomfortable - and they stuck to that decision even after there was a lot of hurt expressed by members of the congregation, who loved that section as a way to grieve and honor loved ones who had contributed to the church.
Overall, there were plenty of good things, but I was simply not able to use most of what was presented in the book because I was either not the target audience or I disagreed with their approach entirely.
