Some five hundred years before the arrival of Emmanuel, the prophet Isaiah prophesied that Emmanuel would come: ” Therefore the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel” (Isaiah 7:14).
Thus, when it was nearing the time for Emmanuel’s arrival, God sent the angel Gabriel to tell the chosen virgin of His plans:
“And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth,
To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary.
And the angel came in unto her, and said, Hail, thou that art highly favored, the Lord is with thee: blessed art thou among women.
And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be.
And the angel said unto her, Fear not, Mary: for thou hast found favor with God.
And behold thou shall conceive in thy womb, and bring forth a son, and shall call his name JESUS” (Luke 126-31).
But when Joseph heard the news, he was distraught.”How could this be? He thought. Mary and I have not come together yet! I must divorce her before everybody finds out.”
“As he considered this, an angel of the Lord appeared to him in a dream. “Joseph, son of David,” the angel said, “do not be afraid to take Mary as your wife. For the child within her was conceived by the Holy Spirit” (Matthew 1:20).
“So it came to pass that there went Joseph up from the town of Nazareth in Galilee to Judea, to Bethlehem the town of David. He went there to register with Mary, who was pledged to be married to him and was expecting a child. While they were there, the time came for the baby to be born, and she gave birth to her firstborn, a son. She wrapped him in cloths and placed him in a manger, because there was no guest room available for them” (Luke 2:4-7).
