* Isaiah 7:14 - Therefore the Lord Himself shall give you a sign; Behold, a virgin shall conceive, and bear a Son, and shall call His name Immanuel (or Emmanuel - see Matt. 1:23 below).
* Isaiah 9:6-7 - For unto us a Child is born, unto us a Son is given: and the government shall be upon His shoulder: and His name shall be called Wonderful Counselor, The Mighty God, The Everlasting Father, The Prince of Peace. Of the increase of His government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even forever. The zeal of the LORD of hosts will perform this.
* Matthew 1:23-25 - Now the birth of Jesus Christ happened this way: When as His mother Mary was engaged to Joseph, before they came together, she was found with Child of the Holy Ghost. Then Joseph her husband to be, being a just man, and not willing to make her a public example, was minded to put her away privately. But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, son of David, fear not to take unto you Mary as your wife: for He Who is conceived in her is of the Holy Ghost. And she shall bring forth a Son, and you shall call His name JESUS: for He shall save His people from their sins. Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying, Behold, a virgin shall be with Child, and shall bring forth a Son, and they shall call His name Emmanuel, which being interpreted is, God with us (see John 1:1, 14). Then Joseph, being raised from sleep, did as the angel of the Lord had instructed him, and took unto himself Mary as his wife: and he knew her not till she had brought forth her firstborn Son: and he called His name JESUS.
* Luke 1:30-35 - And the angel said unto her, Fear not, Mary: for you have found favor with God. And, behold, you shall conceive in your womb, and bring forth a Son, and shall call His name JESUS. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto Him the throne of His father David: and He shall reign over the house of Jacob forever; and of His kingdom there shall be no end. Then said Mary unto the angel, How shall this be, seeing I know not a man? And the angel answered and said unto her, the Holy Ghost shall come upon you, and the power of the Highest shall overshadow you: therefore also that Holy One which shall be born of you shall be called the Son of God.
The Son of God became man so that we could become the children of God!
