This book is similar in nature to the book "unChristian," though it is well worth the time to read it. It does have some very unique perspectives, and is not based on "professional research," but on the author's "personal relationships" with those outside the church. Dan Kimball makes you want to leave your office and go sit in a Starbucks somewhere and meet people who are outside of Christianity (not that the only people at Starbucks is non-Christians).
"They Like Jesus But Not The Church" is an inspiring book, and is presented, I feel, in a spirit of humility and honestly - and those are two traits that are hard for many authors to connect it seems. This book "speaks the truth in love," like the Bible says we should, and it does so both to Christians and non-Christians. Kimball doesn't say, "We have to change everything to reach this generation." But neither does he say, "We don't need to change anything." Instead, the reader is given a great balance between what are the "perceptions of non-Christians" and what are the needed "practices of Christians."
If you want to reach a new generation, you would do well to pick up this book and devour it. This is a book that I am sure I will read again and again.
