The first [sign of holiness in today’s world] is solid grounding in the God who loves and sustains us. This source of inner strength … makes it possible for us, in our fast-paced, noisy and aggressive world, to give a witness of holiness through patience and constancy in doing good. It is a sign of the fidelity born of love, for those who put their faith in God can also be faithful to others. They do not desert others in bad times; they accompany them in their anxiety and distress, even though doing so may not bring immediate satisfaction.
