He is God's love come down from heaven to dwell in human flesh. God so loved the world that He sent His one and only Son. Jesus entered this world, under orders from the Father, to proclaim His love by His words and His works. Jesus preached the Father's love, and He worked the Father's love - healing the sick, releasing the demonized, raising the dead, forgiving sins, dying on the cross. The coming of Jesus into the world was as light shining into darkness.
Darkness does nothing to receive light or prepare for the light.
Light simply shines into the darkness, and the darkness is scattered. The dead do nothing to receive life. God breathes his life into the dead, and death is no more. This dark and dead world did nothing to prepare for the Son of God. He simply made His entrance as the Child of Mary, the Infant of the manger, the preacher from Galilee, the Man of the cross.
