You can't have a story without tension and conflict, without things going wrong. Unanswered prayers create some of the tensions in the story God is weaving in our lives. If God is composing a story with our lives, then our lives are no longer static. We aren't paralyzed by life; we can hope.
Learning to pray doesn't offer you a less busy life; it offers you a less busy heart.
Paul C. Miller, "A Praying Life," pages 22, 25
