Mark 1:23 - Meaning and Application

As soon as Christ began to preach, he also began to work miracles to confirm his teaching. Those miracles matched the purpose of his message, which was to defeat Satan and heal sick souls.

Here we have Christ casting a demon out of a man who was possessed, in the synagogue at Capernaum. Matthew does not tell this story here, though Luke records it later (Luke 4:33). In the synagogue there was a man with an unclean spirit, that is, a spirit that had taken control of him and led him where it wanted. The devil is called unclean because he has lost all purity, because he works against the Holy Spirit, and because he spreads moral corruption through his suggestions.

This man was in the synagogue, and he did not seem to come there to learn or to be healed. Some think he came to confront Christ, oppose him, and keep people from believing in him. When the unclean spirit saw Christ, it cried out in fear and agony. Devils believe and tremble, but they have no hope in Christ and no love for him.

We are told what the spirit said in Mark 1:24. It does not try to bargain with Jesus or make peace with him. It speaks like one who knows his doom. It calls him Jesus of Nazareth, likely to lower people’s thoughts of him, since nothing good was expected from Nazareth. It also says, by force of confession, that he is the Holy One of God, much like the spirit of divination later called Paul and his companions servants of the most high God (Acts 16:16-17). People who only know that much about Christ, but do not trust or love him, go no farther than the devil does.

The spirit also admits that Christ is stronger than it is. In effect, it says, “Leave us alone, for if you deal with us, we are ruined.” That is the misery of evil spirits, they keep rebelling even while they know rebellion will end in their destruction. It also wants nothing to do with Jesus, because it despairs of being saved by him and fears being destroyed by him. Those who say to the Almighty, “Depart from us,” speak the same language.

Jesus wins the victory over the unclean spirit. This is why the Son of God appeared, to destroy the works of the devil (1 John 3:8). Satan cannot stop him with flatteries or threats. So Jesus commands with authority. He rebukes the spirit, tells it to be silent, and orders it to come out. Christ has no use for a demon’s confession when it is only a cover for evil. Some may speak well of Christ while using religion to hide harmful plans. Jesus will silence such speech and put it to shame.

But the spirit must also leave the man, and that is what it feared most. It cannot keep doing more harm. So it throws the man into a violent convulsion. It tears him and cries out loudly, as if trying to frighten the crowd and seem stronger than it was. In the same way, when Christ delivers souls by his grace, Satan often causes a sharp struggle and much distress. He cannot destroy those he can no longer hold, so he disturbs them.

This miracle deeply affected the people. They were all amazed. It was clear beyond doubt that the man had been possessed, and it was just as clear that Christ had forced the spirit out by his own authority. That made them ask one another, “What new teaching is this?” They saw that this teaching must be from God, because it was confirmed in such a powerful way. If Jesus had authority over unclean spirits, then he surely had authority over human beings too.

The miracle also spread his reputation through the surrounding region of Galilee, which was about a third of the land of Canaan. People quickly talked about it everywhere, and they passed along the question, “What new teaching is this?” So many concluded that he was a teacher sent from God. In that light, he appeared more glorious than he would have if he had come with the outward splendor and power the Jews expected from the Messiah. This also helped prepare the way for him now that John, his forerunner, had been imprisoned. The report spread even farther because the Pharisees, who hated his growing reputation, had not yet started saying that he cast out demons by the power of the prince of demons.
