This is the season of preparation for the coming of the Christ Child. As St. Paul said in Galatians 4:4 "But when the fullness of the time was come, God sent forth his Son". In his book, Time, Science, and Society in China and the West, Nathaniel Morris Lawrence suggests a metaphor in which "fullness of time" can be thought of as the moment before delivery in a pregnancy. During advent, the universe is pregnant. All of history has led up to this moment, when the God of time and creation takes upon himself our nature, becomes enfleshed, and steps into our timeline, into the specific time and place of Bethlehem circa 4 BC. The universe is pregnant, awaiting this moment. Mary, the future mother of Jesus, is pregnant, awaiting the delivery of her child. The people of Israel are expecting a messiah. The moment is almost upon us.
