As the disciple whom Jesus loved put it so eloquently:
The true light, which enlightens everyone, was coming into the world. He was in the world, and the world was made through him, yet the world did not know him. He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. [John 1:9-14, ESV]
Merry Christmas, and may the knowledge of the Word become flesh dwell in your heart and your house this holiday.
