We wish each other a merry Christmas, a joyful Christmas, a peaceful Christmas. But a disruptive Christmas? That might be the last thing we need this December. And yet, whenever God shows up in our world and in our lives, that’s exactly what it is: disruptive. His arrival upends everything. This week we see how God establishes an eternal kingdom that disrupts succession. Whether it’s the royal bloodlines of a monarchy or the election cycles of democracy, rulers are always replaced by other rulers. A given ruler might be great, but he may be replaced by one who is terrible. In Jesus, however, God has established an eternal kingdom. The child born to Mary rules that kingdom for the good of all.
