Therefore, you will be given this sign by the Lord himself: The virgin will be with child, and she will give birth to a son, and she will name him Immanuel.
All this took place in order to fulfill what the Lord had announced through the prophet: “Behold, the virgin shall conceive and give birth to a son, and they shall name him Emmanuel,” a name that means “God is with us.”
The birth of Jesus Christ occurred in this way. When his mother Mary was engaged to Joseph, but before they came to live together, she was found to be with child through the Holy Spirit.
Peter answered, “Repent, and be baptized, every one of you, in the name of Jesus Christ so that your sins may be forgiven, and you will receive the gift of the Holy Spirit.”
