A great interview by Bill Hybels of World Vision President Rich Stearns, about his poverty, his rise to worldly riches, his call to a greater cause, and World Vision's challenge to us all.
Stearns has wrote a book called The Hole in Our Gospel

I'm also reading Francis Chan's book, Crazy Love. Both the book and this interview will give you plenty to wrestle with.
