Three Generations: Riding the Waves of Change in Your Church

Definitely, an excellent resource and relevancy up to this year (2005) for Christian ministry and Anthropology in genera! However, out of curiosity, I wonder if Rick Warren (author of "The Purpose Driven Church"), read this book prior to writing his book back on 1995, since most of the concepts and insights portrayed in "Three Generations" are not only addressed in Rick Warren's book. But Also, Rick seems to have mastered Mr. McIntosh research detailed in his "Three Generations". God Bless such extraordinary works such as "Three Generations" and Rick Warren for the implementation of the concepts and insights reveled in it.
