It has long been established in Christian thought that the only way we can know the Infinite God of the Universe is that He would choose to make Himself known to us.  He revealed Himself through the patriarchs and prophets, but the fullness of His revelation came through His Son when He entered the stream of human history.  Born of the Virgin and laid in a manger, He is the God-Human.  This is God’s chosen manner of making Himself known!

“God, after He spoke long ago to the fathers in the prophets in many portions and in many ways, in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.  And He is the radiance of His glory and the exact representation of His nature, and upholds all things by the word of His power. When He had made purification of sins, He sat down at the right hand of the Majesty on high.” Hebrews 1:1-3 (NASB)
