Luke records two conversations with Gabriel the archangel, one with Zechariah the father of John the Baptist and one with Mary the mother of Jesus. Zachariah and Elizabeth were praying a long time for a child, but when Gabriel announced the answer to their prayers Zachariah did not believe. And so he was mute because of his unbelief until John was born. In Mary’s conversation with Gabriel she also had questions but responded by saying that she is the servant of God and to let it be according to His will. Like the Old Covenant old and expiring, Elizabeth bore John in her old age. Like the New Covenant, Mary was in her youth. Like ancient Israel under the Old Covenant, Zachariah approached the situation in disbelief. Like the New Covenant, Mary approached the situation in faith (Luke 1:38).
