The story of Zachariah's encounter with Gabriel and the birth of John the Baptist is a powerful reminder of the coming Messiah. Zachariah's song of prophecy, filled with Old Testament passages and allusions, foretells the ministry of his son, who will prepare the way for the Messiah. The Messiah's ministry will bring light to those in darkness, rescue those facing death and judgment, and give inner peace to those who have none.
