Here's a quote from Rich Mullins that I thought was good.
"Jesus said whatever you do to the least of these my brothers you've done it to me. And this is what I've come to think. That if I want to identify fully with Jesus Christ, who I claim to be my Savior and Lord, the best way that I can do that is to identify with the poor. This I know will go against the teachings of all the popular evangelical preachers. But they're just wrong. They're not bad, they're just wrong. Christianity is not about building an absolutely secure little niche in the world where you can live with your perfect little wife and your perfect little children in a beautiful little house where you have no gays and minority groups anywhere near you. Christianity is about learning to love like Jesus loved and Jesus loved the poor and Jesus loved the broken."
