Every one of us has a "good work" to do in life, which accomplishes something needed in the world while completing something in us. When it is finished a new work emerges which will help us to make green a desert place, as well as to scale another mountain in ourselves. The work we do in the world, when it is a true vocation, always corresponds in some mysterious way to the work that goes on within us.
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.
