Martin Luther once said, “Where Christ builds a church, there the Devil builds a chapel.” It shouldn’t surprise us then that whenever Jesus stands up to speak, the Devil would try to silence or overwhelm those words. It shouldn’t surprise that we have a demon-possessed man right there in church interrupting Jesus’ sermon. Nor should we be surprised if the devil shows up among us. But here is the power. As we gather for worship, we gather for war. Not just out there but in here too. And each time, Jesus stands up: “Silence! Be Still.” And he must. The Devil must flee before the Word of God. A sermon on Mark 1:21-28.
