I heard Tony Campolo say something once that, for whatever reason, was running through my head today. He was talking about how his mother that had always told him, "...you were not brought in to this world to be happy. You were brought in to this world to be good."
Then he went on to talk about how such a philosophy is so at odds with the society we live in, which pretty much revolves around a really shallow take on happiness (ie: decrease pain, increase pleasure). But he talked about being good. Not a cheap keep-a-long-list-of-rules kind of goodness, but to live a life that radiates the goodness, kindness, compassion, justice, and mercy of a "good" God.
I just find that so inspiring.
