Simple Spirituality by Christ Heuertz is a small book but it packs a huge punch. Chris, as International Director of Word Made Flesh, has devoted his life to serving the world's poor including folks who are enslaved. As he guides his readers though five steps of being able to see the world as God sees it, your heart will break and you're going to feel pretty crummy for being born American. The whole camel passing through the eye of a needle thing will ring in your ears as he leads you to a place of having your heart broken for the "least of these". It's a dangerous book but I highly recommend it. You will be wracked with questions afterward. Why? What? How?
