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.
The function of faith is not to reduce mystery to rational clarity, but to integrate the unknown and the known together in a living whole, in which we are more and more able to transcend the limitations of our external self.
~ from NEW SEEDS OF CONTEMPLATION by Thomas Merton
