If we desire a simple test of the quality of our spiritual life, a consideration of the tranquility, gentleness, and strength with which we deal with the circumstances of our outward life will serve us better than anything that is based on the loftiness of our religious notions, or fervor of our religious feelings. It is a test that can be applied anywhere and at any time. Tranquility, gentleness, and strength, carrying us through the changes of weather, the ups and downs of the route, the varied surface of the road; the inequalities of family life, emotional and professional disappointments, the sudden intervention of bad fortune or bad health, the rising and falling of our religious temperature. Tranquility, gentleness, and strength are the threefold imprint of the Spirit on the souls surrendered to his great action.
~ The Spiritual Life, Evelyn Underhill
