When Jesus saved one of the demon-possessed, the audience became astonished, but some of them blasphemed, accusing Christ of leaguing with the ruler of the demons in whose name he cast out demons. They called this ruler, "Beelzebub" i.e. "Lord of flies" who seemingly had spirits as countless as the flies of the world. The multitudes encouraged Jesus to make a miracle or a work above mere human power, other than his ordinary healings to try his divine power that he might rebut the charge of his relation with demons.
But Christ pierced his enemies with his reply, and revealed to them some secrets of hell that are so simple that any human mind could understand them. A demon cannot cast out a demon, for unclean spirits are a fearful union. In spite of their hatred, yearning for independence, and intent to destroy all men, they cannot do what they will, but are prepared "in Satan" who is the spirit of the antichrist authority. This evil one is not divisible against himself. He dwells in his followers, and binds them in eternal bondage in his kingdom of destruction.
In the Old Testament, the Jews cast out demons in the name of the Lord God, for Satan runs away if men came near to God. The evil one moves away where man is faithful to his Lord. Christ testified of the righteous power of the believers of the Old Testament who will condemn those who deny Christ in the Last Judgment, for they rejected the signs of his divine power.
Then Jesus described how he cast out demons. He is the King of the worlds and heavens, sitting in the throne of his glory who does not utter any word in the face of Satan, but with mere movement of his finger, the hosts of evil run away quickly drifted into hell, leaving the demon-possessed. In this parable, Christ mocked at the power of Satan who was like an army equipped with the latest weapons, guarding his barracks, imprisoning and enslaving whoever comes near his expanses. Today, he entices millions of people into unbelief in God, worship of modern idols, and blasphemy that they may be filled with his evil spirit and become his slaves, as Christ said, "Whoever commits sin is a slave of sin."
But now, everything is changed, for Christ came to our world, overcame the evil ruler, took from him all his armour: haughtiness, selfishness, injustice, impurity, hatred, and lying, and released his slaves. Every believer in Christ is delivered from the authority of Satan, and armed with the weapons of the Holy Spirit: love, joy, peace, patience, humility, service, faith, abstinence, and truth. As the followers of Satan are an evil union, so we became in Christ a holy union. Every believer is secured and protected forever. Did you resort to Christ and abide in your Savior?
The Jews of the Old Testament could cast out demons in the name of the Lord, but they neither overcame the evil one himself, nor gave the delivered a new power. So he that was delivered became fresh again in body and in spirit, but later on the evil spirit would come back to him, accompanied with seven other spirits even worse than himself, and they come and live in that poor man. So when it is all over, that man is in worse state than he was at the beginning. In (Luke 8:26-39) we read Luke’s report about a possessed man whom Christ delivered completely. Christ granted us complete redemption from Satan. He can cast demons into hell (4:34; 8:31), and establish his Holy Spirit instead of unclean spirits in men, and thus their bodies become filled with the Spirit of the Lord with no empty place for foreign spirits. Are you filled with the Holy Spirit? Which spirit dwells in you?
In the midst of this struggle between the spirits, a woman of the company beatified the Virgin Mary, his mother. Christ did not reject this beatitude, but demonstrated the true glory in those who heard the words of the living God, moved them into their hearts, kept them, and lived accordingly. Satan is overcome not by Mary, but by Christ alone. Christ does not teach us to follow his mother, but to penetrate deeply into his words that their power may convert us, deliver us from Satan, and strengthen us to overcome the demons around us in his name.
