A person who sees things as they truly are and sympathizes with pain and sorrow is capable of touching life’s depths and finding authentic happiness. He or she is consoled, not by the world but by Jesus. Such persons are unafraid to share in the suffering of others; they do not flee from painful situations. They discover the meaning of life by coming to the aid of those who suffer, understanding their anguish and bringing relief. They sense that the other is flesh of our flesh, and are not afraid to draw near, even to touch their wounds. They feel compassion for others in such a way that all distance vanishes. In this way they can embrace Saint Paul’s exhortation: “Weep with those who weep” (Rom 12:15 ). Knowing how to mourn with others: that is holiness.
