It's been years since I've seen the movie Chariots of Fire. But one scene sticks with me. Eric Liddell is explaining why he wants to keep running. "God made me fast," he said. "And when I run I feel God's pleasure."
Why study when I could have a less intense hobby? It's simple. When I study, I feel God's pleasure.
What has God made you to do? What do you do that makes him smile?
