I've recently become something of a runner, and the more I've done it, the more convinced I've become that the running metaphors one finds all over the New Testament work quite well.
But every once in a while, it feels like flying.
But you'll do it faster and better with other people.
You're not doing it hard enough.
They wonder why the hell you would bother.
Especially if you look like it's not coming easy to you.
And easy to quit.
You're totally going to get caught.
The harder it is to quit.
