God became Man

"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" (Matthew 1:23, prophesy from Isaiah 7:14)

In the beginning was the Word, and the Word was with God, and the Word was 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 1:1, 14).

Merry Christmas!
