All this is simply to say that all life is interrelated. We are caught in an inescapable network of mutuality; tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. As long as there is poverty in this world, no one can be totally rich even with a billion dollars. As long as diseases are rampant and millions of people cannot expect to live more than twenty or thirty years, no one can be totally healthy, even with a clean bill of health from the finest clinic in America. Strangely enough, I can never be what I ought to be until you are what you ought to be. You can never be what you ought to be until I am what I ought to be. This is the way the world is made.
To interpenetrate an entire human life with divine life, it is not enough to kneel once a year in front of the crib and let oneself be moved by the charm of the holy night. One needs to live one's entire life in daily communication with God, to listen to the words that God has spoken and that have been transmitted to us, and to follow these words.
