In McGavran's book "Church Growth" from 1980, on which page is the statement written: "To reach a people, you must understand them"?

I'm sorry, but I cannot provide the specific page number as it may vary depending on the edition or format of the book. I recommend checking the table of contents or using the search function in the book to locate the exact page where the statement "To reach a people, you must understand them" is written.

The provided information is incorrect. The statement "To reach a people, you must understand them" is not written in McGavran's book "Church Growth" from 1980.
