John 1-2: As Many As Received

Two of the gospels, Matthew and Luke include Jesus' genealogy in the story of his birth.  The Gospel of John begins with Jesus' genealogy as well, but with hints of the prophet he will become, John tells Jesus' genealogy from a different perspective.  He has listened to Jesus' descriptions of the kingdom of heaven and realizes that there is another more significant reality than the one limited by our earthly world view.
 In the beginning was the Word, and the Word was with God, and the Word was God.
 The same was in the beginning with God.
 All things were made by him; and without him was not any thing made that was made.
 In him was life; and the life was the light of men.
 And the light shineth in darkness; and the darkness comprehended it not. - John 1:1-4 KJV

There you have it, the story of Jesus' genealogy and the story of the known world from creation to today.  Jesus was there all along.  He was at the creation.  He is the source of life.  He came to tell us of that life and the world could not accept it.  He came, he appeared as light in the darkness for a brief moment, but the world would not accept him.  The world always has and always will love darkness better than life. 
 He came unto his own, and his own received him not.
 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. - John 1:11-14 KJV

John, the disciple, received Jesus as the Son.  He was witness first hand to the miracles, beginning with turning the water into wine.  John, the Baptist, received Jesus as the Son.  He saw the Spirit descending on him like a dove. Many others who witnessed his miracles received him as well.  Now while he was in Jerusalem at the Passover Festival, many people saw the signs he was performing and believed in his name.  But Jesus would not entrust himself to them, for he knew all people. He did not need any testimony about mankind, for he knew what was in each person. - John 2:23-25 NIV

Jesus knew who he was, and he knew what people were.  He did not need any testimony.  The ones who received him became the sons of God.  The ones who did not receive him did not.
