J.I. Packer said the Incarnation is the supreme mystery of the Gospel. Jesus was God made man. He took a human nature without loss of deity. Jesus is the eternal Word made flesh. All things were made through Him (Col 1:16). He came to us as the true light, yet He was rejected by many of His own people. This rejection ultimately led to the Cross. But that was His mission. He came to be the atoning sacrifice for His own. He came to die in our place.
This is why the Word became flesh. He was humiliated so that we would be raised up on the last day. The staggering truth of the Incarnation is meant to drive us to worship, to cause us to glorify God for His mercy (Rom 15:8-9).
