The classic longings motivate a sound life; so do faith and gratitude. Of course, all these things fail from time to time. Spiritually healthy people know very well the drag of sloth and doubt. They know about spiritual depression. They know what it is like to feel keenly that the world has been emptied of God. That is why a spiritually sound person disciplines her life by such spiritual exercises as prayer, fasting, confession, worship, and reflective walks through cemeteries. She visits boring persons and tries to take an interest in them, ponders the lives of saints and compares them to her own, spends time and money on just and charitable causes. A person of spiritual hygiene covets the virtues and character strengths that Christians since Paul have always prized —compassion, for example, and patience. She seeks these and other excellences —endurance, hope, humility, forthrightness, hospitality. She then tries to work them into a regular practice routine, always aware that in order to grow in these excellences she needs both to strive for them and to fail in her striving. 47 She needs to persist through striving and failure and growth in order to become a free and joyful contributor to shalom.
