John 1:1-5 says,
"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.Jesus Christ is the Word; the Divine Logos; the Light of the World.
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."
All things were made by Him, so only by Him could a fallen world of darkness, corrupted by Adam's sin, be reconciled to a Holy & Just God.
And into this darkness, Jesus was born of woman - 'The Son of Man.' He was tempted and suffered just like every man, so we have commonality to His humanity, but He is Just and Holy.
Jesus said to Pilate, "For this cause I was born, and for this cause I have come into the world, that I should bear witness to the truth." But the darkness comprehended it not.
And so, we come full circle with 'come into the world.' Merry Christmas.
