The height of greatness if not how far one rises, but how low one bends to serve another.
I wonder what Paul was really like. If he were in our church, what would we think about him? He was amazingly intense, and incredibly focused. He never hesitated to challenge others. I doubt he'd be the guy who'd just piddle around much. Not that it's necessarily wrong or sinful, but I don't see him playing video games or watching television till the early morning hours.
