Luke 1 recounts the story of an angel visiting Zachariah announcing the birth of his only son. After years of desiring a child, he and Elizabeth will give birth to one who will prepare the way for Messiah. This special child will be like Elijah, a messenger for Yahweh, preparing the people of God for Jesus. This angelic encounter begins the fulfillment of Isaiah, Malachi and others who promised that one day a messenger would come who would turn the hearts of the fathers back to their children, and the people of Israel back to their God. John prepares the way for Jesus.
