I waited with anticipaton to read his book and was not disappointed. In fact, I was humbled, challenged, and inspired. And now I can read more of Ed Gilbreath's thoughts on his new blog. Check it out.
Also, Tony Campolo has some fascinating thoughts on wealth, poverty, and faith. Read it, and read it again. (HT: Scot McKnight) In light of Campolo's thoughts, I'd also recommend Fr. Gary Smith's Radical Compassion: Finding Christ in the Heart of the Poor (Loyola Press, 2002). There is also an interesting on-line study guide for the book here.
