There is rest to be had in ministering to others. As Tim Keller points out, there is a freedom to self-forgetfulness. Serving others, fulfilling others’ needs, actually fills you. But there is a rhythm that’s modeled for us in the Bible. After fashioning everything from nothing, God set aside one entire day for rest. God rested to show that he was God and that His creation was good. When we enter into that rest, we too are renewed by the understanding that God is God and that His creation is good. When I rest, I realize, shockingly, that the world doesn’t depend on my awesomeness in order to continue. It depends on God’s.

And that’s the paradox of being human. We love freedom—but we use it to enslave. Today’s freedom fighter is tomorrow’s oppressive dictator. We are “bent,” as C.S. Lewis put it, towards destruction and we use our power to take it away from others. Not only do we enslave others, but also we allow ourselves to be enslaved by meager things. I rush around, looking for something else to occupy my time and entertain me and fulfill me and satisfy me. We enslave—we are enslaved.
