I did not like this book. I thought "Introduction To Global Missions," by Pratt, Sills, and Walters was a much more thorough treatment of Cross-cultural ministry. The fictional narrative of a husband and wife missionary added nothing to the book and was actually incredibly distracting. I also thought that the sections in the book designed to support Rheenens 'missional helix' were just unnecessary. This book lacked substance where it was needed and contained too much fluff where it was not. Great class, terrible textbook.
