This was my first book on missional topics, and Driscoll's book on reformission was helpful as a challenge to live and think missionally in culture. Driscoll stresses that since people do not exist apart from culture, we need to understand and relate to them in that context. He seems to specially challenge evangelicals who have overly distanced themselves from the world and ignored culture while also giving strong critiques of "emerging"-type Christians who have been swept up in culture and lost the distinctiveness of God's call to holiness. Driscoll deals with the connections between culture and the gospel, evangelism, and sin and offers insight into contemporary American culture.
In his typical style, Driscoll tends to paint with a broad brush and bold colors, which is helpful for making his point clearly and forcefully, but at times it feels that significant nuances have been missed. The book is not particularly systematic or linear, which is not necessarily a bad thing, but it does make it more difficult for people like me who process that way. Overall, though, the book presents a helpful positive vision of ministry among people in culture and offers helpful categories, concepts, and observations for understanding the multi-hued contemporary American culture.
