Seriously, it has.In many ways, this book confirmed and put together much of what I had been seeing in reading scripture, but I had not heard put in this way before. For 16 years (about half of my life) I was struggling with back pain from a serious bike accident as a high school kid. It affected my focus, my hope, and as my wife once said, I was "living in bubble wrap" at times physically and mentally. The thought of sweeping the floor would inspire a small panic attack on days, and taking the dishes out of the dishwasher required an act of will.While I was not immediately healed as a result of reading this book, I think it was a definite primmer for me in that process. I'm not sure that this is expressly outlined in the book (nor am I recommending a model) but I basically decided to mourn my bike accident like a part of me died, because basically it did. It was clear in my mind as I did this that I was doing it without an expectation of the outcome, but just with a deep sense that I needed to do it. It got messy.As backdrop to this, I had been through different types of christian counseling and generational deliverance (to which there was great value) and I had previously tried to forgive myself and God multiple times over the years. But this was different.I actually visualized what happened, as much as I could remember, and after a while, I was able to get to the point where I was able to say "I accept that this accident happened".As I've told this story to a few people who have gone through some hard things, they will tell you that is a fairly large step. But I didn't sense that I was done. In hindsight I would say as an act of my will I said the following next to the best of my recollection: "Not only do I accept that it happened, but I'm glad that it happened, and I would not have wanted it to happen any other way". As a note, I said that ONLY because I was choosing to believe Romans 8:28 regarding my particular accident and believe "...that in all things God works for the good of those who love him, who have been called according to his purpose.".And that's when I wept like someone died.I'm not sure how long it lasted frankly, and my back was not better the next day, but about 6 weeks later I found hope in a chiropractor with a different process (and I went to him for something else) AND my parents called and said they had come across a physical therapist (that was much more than that and that)and that they really believed that she could help me. Both of them help and 2 months later after a series of only about 4 treatments (related to coiled up muscles, ligaments, and other tissues), I basically can do what I want and don't think about my back.What I could only see once there was a bit of perspective was that once I went through the process of mourning the death of a huge part of my life in the accident, I pretty much had that those things back within 6 weeks AND while I did not recognize it at the time (while I was still stiff, and in "bubble wrap") was that I was not mad about my accident any more.All I can tell you is that once I got to the point I did that night in prayer, I did not have any fingers left to point. Not at myself, not at God or anyone else. So in my experience so far, that one way that I experienced the supernatural power of forgiveness.I think you should read the book.
