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’s voice disrupts silence. Because we have a God who shows up rather than remaining distant, our hearts need constant preparation. That preparation is what the Bible calls repentance. God does not leave us to do that important work alone, however. He patiently sends the sound of his voice into the world through his messengers. Through the proclamation of his law, he produces in our hearts sorrow over sin. Through the proclamation of his gospel, he gives us comfort through our Savior.
