Mary was not the only one to get a pre-birth announcement from an angel. Matthew recorded the dream given to Joseph.
behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” All this took place to fulfill what the Lord had spoken by the prophet:
“Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel” (which means, God with us). (Matthew 1:20–23 ESV)
Joseph also was told about the miraculous conception, less to answer his questions about the biological possibility and more about the legality and the propriety. The angel affirmed that Mary had not been unfaithful.
The angel also told Joseph the child’s name: Jesus. It meant something: “for he will save his people from their sins.” Savior was His name, part of His identity.
The angel also quoted Isaiah, not only to connect Jesus’ origin with the prophecy about a virgin birth, but also as a further part of His identity. He is named Jesus, and Immanuel, meaning “God with us.”
Beloved, the bread and wine before us are signs of the cost of our salvation and signs of the Son’s flesh and blood. We eat and drink in remembrance of Jesus, Immanuel, our Lord.
