In the midst of the deepest guilt and distress of the people, a voice speaks that is soft and mysterious but full of the blessed certainty of salvation through the birth of a divine child (Isa. 9:6-7). It is still seven hundred years until the time of fulfillment, but the prophet is so deeply immersed in God's thought and counsel that he speaks of the future as if he saw it already, and he speaks of the salvific hour as if he already stood in adoration before the manger of Jesus. "For a child has been born for us." What will happen one day is already real and certain in God's eyes, and it will be not only for the salvation of future generations but already for the prophet who sees it coming and for his generation, indeed, for all generations on earth. "For a child has been born for us." No human spirit can talk like this on its own. How are we who do not know what will happen next year supposed to understand that someone can look forward many centuries? And the times then were no more transparent than they are today. Only the Spirit of God, who encompasses the beginning and end of the world, can in such a way reveal to a chosen person the mystery of the future, so that he must prophesy for strengthening believers and warning unbelievers. This individual voice ultimately enters into the nocturnal adoration of the shepherds (Luke 2:15-20) and into the full jubilation of the Christ-believing community: "For a child has been born for us, a son given to us."
