About a month ago I had the opportunity to hear Jim Wallis (and his wife) speak at a workshop in Portland, OR. I was impressed with what he had to say AND how he said it. He was forceful and direct but didn't malign those who disagree with him. His book, God's Politics is still selling well and sits pretty high on the NYT Bestseller list. If you want to know more about him, check out this article from the Washington Times.
