This book is not some sort of self-help manual but a reminder of how the gospel can change us:
I want to be like Jesus. I can observe him in action as I read the Gospels. I can study the life he lived and the love he showed. I could try very hard to imitate him. But at best that would lead only to a small, short-lived improvement, and indeed even that small improvement would probably only make me proud.
I need more than an example. I need help. I need someone to change me. Trying to imitate Jesus on its own only leaves me feeling like a failure. I can’t be like him. I can’t match up. I need sorting out. I need rescuing. I need forgiveness.
The great news is that Jesus is not only my example but also my Redeemer.
I could tell that Chester was on to something, particularly in Chapter 2, when he described three wrong reasons to change: 1) to prove myself to God, 2) to prove myself to other people, or 3) to prove myself to myself.
At the heart of any advice that Chester gives is the theological reality of God and the gospel. For example, he talks about some “reminder phrases” that he uses to help others stay focused on the gospel in the midst of fear:
God is greater than your thought.
Not what if? but what is, and what is, is that God is in control.
The reality of the gospel is that behavior does not justify us before God and, therefore, only changing behavior will always be short-lived and misguided. At the heart of behavior are the affections that motivate those behaviors. To overcome sin I not only have to purge it from my life, I have to replace it with an affection for Jesus alone.
