McGavran's book, first published in 1970, is a missions classic: nothing else so penetratingly analyzes the mechanisms of the spread of the gospel. His skillfull combination of theology, research, sociology, and spiritual insight creates a paradigm for effective evangelism strategy both at home and abroad. In this third edition, C. Peter Wagner has modernized the language and streamlined the flow of ideas, reducing the book's bulk by 35%. 310 pages, paper from Eerdmans.
