How do I take care of the people Jesus calls the hungry and thirsty and naked and tired? I can love them, and when you love the people around you, and truely reach out to them this is how we learn to serve. A recent sermon podcast I listened to from Rob Bell talked about this, and how when we struggle to feel God's presence, and we are solely looking for Him in our intellect or theology, we miss the place He tells us to find Him-in generosity.
God is a generous God-giving a Son who gave His life for the world. Giving is where we need to be in our daily lives, and it doesn't just involve the stuff we thing about. It involved love, care and the feeling of being treated like a human.
