This book is based on three (1) the pastor is the chief catalyst in church growth; (2) there is but so much time in a day, therefore, what the pastor can do is limited; (3) if the church and her leadership do a few things well, God will grow His church. This book is not culturally specific. Nor is it designed, focused, or oriented specifically toward any particular denomination. The only specific is church growth.
I think it is a great book for church leadership to understand how to not spread ourselves to thin in the work of the church. The seven principles make it easy to assess where you are and also how to approach ministry.
