Query: The Best Book I've Read on the Subject of Forgiveness

As far as understanding the nature and power of forgiveness, this was a paradigm shifter for me. More importantly, it moved me to action, literally becoming a catalyst for mending, what was at the time, a seriously damaged relationship. I have not read a better book on the subject. Volf's a deep thinker, but he doesn't have his head in the sand. He writes from a place of humility and grace. And his understanding of the Gospel and what it makes us capable of becoming is so illuminating and life-giving. I hope I don't sound too enamored with the man, but his insights have proven to be very wise. I feel that I am in his debt.
