(When we contemplate the Incarnation of Jesus Christ, The Son of God , the) question spontaneously arises: How is such a thing possible? Is it worthy of God to become a child? To try to open one's heart to this truth that enlightens all of human existence, it is necessary to yield the mind and recognize the limits of our intelligence. In the cave at Bethlehem, God shows himself to us as a humble "infant" to overcome our pride. Perhaps we would have submitted more easily before power, before pride; but he does not want our submission. He appeals, rather, to our heart and to our free decision to accept his love. He has made himself little to free us from this human pretension of greatness that arises from pride; he has incarnated himself freely to make us truly free, free to love him.
Dear brothers and sisters, Christmas is a privileged opportunity to meditate on the meaning and value of our existence. Approaching this solemnity helps us to reflect, on one hand, about the drama of history in which men, wounded by sin, are permanently seeking happiness and a satisfactory meaning to life and death; on the other hand, it exhorts us to meditate on the merciful goodness of God, who has gone out to meet man to communicate to him directly the Truth that saves, and make him participate in his friendship and his life.
Let us prepare for Christmas, therefore, with humility and simplicity, readying ourselves to receive the gift of light, joy and peace that irradiates from this mystery. Let us welcome the nativity of Christ as an event capable of today renewing our existence. May the encounter with the Child Jesus make us people who do not think only of ourselves, but rather open to the expectations and necessities of our brothers. In this way we too become testimonies of the light that Christmas radiates over the humanity of the third millennium. Let us ask most holy Mary, the tabernacle of the incarnate Word, and St. Joseph, silent witness of the events of salvation, to communicate to us the sentiments they had while they awaited the birth of Jesus, so that we can prepare ourselves to celebrate in a holy way the coming Christmas, in the joy of faith and enlivened by the determination of a sincere conversion.
