I first heard about her when I was in a bookstore, looking in the religion and spirituality section, and came across her book "Accidental Saints: Finding God in All the Wrong People", which I later purchased and enjoyed greatly. She's not the image that comes to mind when one thinks of a pastor, she's extremely rebellious and has had a bit of a troubled history. With so much (justly deserved) anger towards Christians these days, she is one of the good ones, the ones who get it right.
Some people commented that this video suggests letting bad people off the hook for bad things, but I see it as another way of practising non-attachment, in this case, with negativity. Forgiveness isn't just about "letting people off the hook", it's also about freeing oneself from one's own mental prison of anger. It was only recently that I was able to forgive myself for my own errors - that seemed harder to me for some reason than forgiving others for theirs, as I have had to live with myself and certain ideas going around in my head for a very long time now. Prayer made it easier - for the longest time, I thought I would never get it right!
Here is a link to her website: Nadia Bolz-Weber ... the book I read by her is worth the read, and I hear the others she's written are as well.
