We're using this as our adult SS book this fall. Three couples (us included) are also using it as a book study once a month or so in one of our homes. It's incredible and quite funny! Highly recommend this book to all.
This book by Kevin is life altering. He makes you think about your commitment to Christ. He defines being a fan vs. being a follower. It makes you look at passages of Scripture and see the true reality in your own life and how to follow Christ is to deny yourself daily and pick up the cross and follow.
