Luke 1:26–38 relates how a virgin learned she would miraculously bear the Son of God. The angel Gabriel comes to Mary, who is engaged to a man named Joseph. Gabriel tells Mary that she will bear a son, to be named Jesus. He will be the Promised One long awaited by the people of Israel. Since Mary has never been intimate with a man, God will miraculously conceive the child. Gabriel is the same angel who predicted the birth of John the Baptist (Luke 1:13), and he informs Mary about this happy occurrence for her relative, Elizabeth. Mary responds in submissive faith. A parallel account is found in Matthew 1:18–25.
