“Gratitude is not a simple emotion or an obvious attitude. It is a difficult discipline to constantly reclaim my whole past as the concrete way in which God has led me to this moment and is sending me into the future. It is hard precisely because it challenges me to face the painful moments – experiences of rejection and abandonment, feelings of loss and failure – and gradually to discover in them the pruning hands of God purifying my heart for deeper love, stronger hope, and broader faith.” ~Henri J. M. Nouwen, Spiritual Formation: Following the Movements of the Spirit
