Jesus rebuked him, saying, "Be quiet, and come out of him!"
The unclean spirit, convulsing him and crying with a loud voice, came out of him.
They were all amazed, so that they questioned among themselves, saying, "What is this? A new teaching? For with authority he commands even the unclean spirits, and they obey him!"
The report of him went out immediately everywhere into all the region of Galilee and its surrounding area.
What does this reveal about Jesus?
Jesus is Lord over demons
Notes & Applications:
If only Christians would submit to the Lordship of Christ as demons do in His presence! Jesus tells him to be quiet. I don't think he wanted demons on his evangelism team. It's not necessarily good advertisement having demons as your spokesmen. But what can be inferred from this interaction is Jesus' authority in the spiritual realm. The fear that he invokes among demons is due to him being the judge who will ultimately cast these into the lake of fire to be tormented. Satan does not rule hell, Jesus does!
