These elderly parents had dreamt of that day and even prepared for it, but they no longer expected it: they felt excluded, humiliated, disappointed: they had no children. Faced with the announcement of the birth of a son, Zechariah had remained incredulous, because the natural laws did not allow it: they were old, they were elderly; consequently the Lord rendered him mute throughout the entire gestation period.
It is a sign. But God does not depend on our logic and our limited human capacities. We must learn to trust and be silent before the mystery of God, and to contemplate in humility and silence his work, which is revealed in history and which so often exceeds our imagination.

Here is an empty cradle, we can look at it. It can be a symbol of hope because the Child will come, it can be a museum object, empty all our lives. Our heart is a cradle. What is my heart like? Is it empty, always empty, but is it open to continually receive life and give life? To receive and be fruitful? Or is it a heart preserved like a museum object that has never been opened to life and to give life?
