Henri Nouwen, The Way of the Heart –

The discipline of leading all our people with their struggles into the gentle and humble heart of God is the discipline of prayer as well as the discipline of ministry. As long as ministry only means that we worry a lot about people and their problems; as long as it means an endless number of activities which we can hardly coordinate, we are still very much dependent on our anxious and narrow heart. But when our worries are led to the heart of God and there become prayer, then ministry and prayer become two manifestations of the same all-embracing love of God.
