So what is Christmas all about? Without giving a lecture or sermon.
Christmas is God opting into the messiness of the world and not exempting himself from it. (Me)
The former Bishop of Durham, David Jenkins, put it like this:
God is. God is as he is in Jesus. So, there is hope.
Like a stone on the surface of a still river, driving the ripples on for ever, redemption rips through the surface of time in the cry of a tiny babe.
