It is not difficult to work courageously when you believe that your actions will turn the tide and bring about change. It is another thing altogether to act courageously without the expectation that you will change the world. Such a courage is the paradox at the center of this chapter, this book, and the Christian life. In action we try to be self-sufficient, autonomous. Often, we act because we don’t trust that we will be preserved otherwise. But our calling is to “be still and know” that God is God, and not you (Psalm 46:10).
