Given, then, that there were no positive additions to the experience of the Son, but only negative ones, why would he do it? Why would the perfect joy of divine life be relinquished in order to be publicly executed as a loathed criminal? There is only one answer. Love.
There is one passage that each of us will hear a dozen times over Christmas: ‘For unto us a child is born, for unto us a Son is given…And he shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace’ (Is. 9:6). There is a puzzle in this verse that a lot of Christians never pause to figure out. What does it mean that Jesus is ‘Everlasting Father’?
The work of the incarnation is not complete until each and every adopted child of God is perfectly refashioned into the image of the Maker. Jesus did not live a perfect life simply so that he could enjoy communion with the Father. He lived a perfect life so that you and I could be restored in communion with the same Father. His work is not finished until he has resurrected the beauty of our nature from the ashes of our sin.
