Idleman basically frames the book as a time to sit down and define the relationship between you and Christ. The book forces you to think through the question, "Am I a fan or a follower?" Do I really like Jesus and what he does from a distance? Or is my entire life centered around him? Is he my Lord or someone that I really look up to?
The questions in this book are challenging. Honestly asking them of yourself can be difficult. We need to ask these questions, though. Whether or not we are committed followers of Christ is the most important thing we have to consider.
