“All change comes from deepening your understanding of the salvation of Christ and living out of the changes that understanding creates in your heart. Faith in the gospel re-structures our motivations, our self-understanding, our identity, and our view of the world. Behavioral compliance to rules without heart-change will be superficial and fleeting.”
– Timothy Keller, The Prodigal God (new York, NY: Dutton, 2008), 121.

Hi Craig,
I am reading the Fellowship of the Ring right now! Anyway, I think this quote is very true. I keep going back to things in the Gospel that change my thinking in so many areas.
