Jesus has authority over everything. To the demons He says “Get out” and they do. They know who Jesus is. They obey Him.
They also know why Jesus had come. Jesus, my Master, came to destroy the evil ones. And Jesus has. Jesus died for me. Jesus was buried like a man. Jesus, the son of our Heavenly Father, was raised up from the dead. Jesus is victorious. Jesus ascended into heaven and now sits at the right hand of God, ruling over all things.
Then they entered Capernaum. When the Sabbath arrived, Jesus lost no time in getting to the meeting place. He spent the day there teaching. They were surprised at his teaching—so forthright, so confident—not quibbling and quoting like the religion scholars.
Suddenly, while still in the meeting place, he was interrupted by a man who was deeply disturbed and yelling out, “What business do you have here with us, Jesus? Nazarene! I know what you’re up to! You’re the Holy One of God, and you’ve come to destroy us!”
Jesus shut him up: “Quiet! Get out of him!” The afflicting spirit threw the man into spasms, protesting loudly—and got out.
