Because God surprises earth with heaven by sending his only Son as
light shining in the darkness; because in Christ the holy city comes into our
midst; because the Jewish child in the manger is the impinging of eternity upon
time and thus the movement of the eternal to be with us; because he is that
light by which the nations may walk and by whose grace and power they are
healed – because of all that, your words and your acts, your decisions between
greed and grace, between lies and truth, can in their turn become the impinging
of heaven upon the hell that we make of our world.
