The Authority and Power of Jesus Over Demons


by Albert Kang

As Jesus began his public ministry, the Gospels recorded a remarkable encounter that revealed his sovereign authority over the demonic realm. In the synagogue, Jesus confronted a man possessed by an unclean spirit (Luke 4:33-36). When the demon sensed the presence of its mortal enemy, it cried out in protest, “Ha! What have you to do with us, Jesus of Nazareth?” (Luke 4:34). But rather than engaging the demon in debate, Jesus responded with unwavering command, saying, “Be silent and come out of him!” (Luke 4:35).

This incident is deeply instructive, for it demonstrates a fundamental truth about spiritual warfare. Demons may hate God and defiantly resist His will, but they are ultimately powerless against the sovereign authority of the Son of God. As the text states, “the demon had thrown him down in their midst, he came out of him, having done him no harm” (Luke 4:35). The onlookers were left “amazed” at the sheer power of Jesus’ words (Luke 4:36).

What accounts for this remarkable display of dominance over the demonic? The key lies in the distinction between God’s moral will and His sovereign will. The moral will of God is revealed in commandments like the Ten Commandments. These instructions are the ethical precepts that demons will brazenly defy. But there is another aspect of God’s will, His sovereign will, which demons are totally powerless to resist.

When God exercised His sovereign will and said, “Let there be light,” light came into being. When Jesus commanded, “Lazarus, come out,” the dead man could not resist the command of life into his dead body and got up to walk out of the tomb. And when Jesus declared to the unclean spirit, “Be silent and come out of him,” the demon had no choice but to obey. This is the authority and power that left the people in the synagogue utterly astonished.

The implications of this truth are profound. As followers of Christ, we need not cower in fear before the forces of darkness. For we serve a Savior who has been given “all authority in heaven and on earth” (Matthew 28:18). When we stand firm in our faith and invoke the name of Jesus, even the mightiest demons must submit to His sovereign command.

In Luke 9:1-2, we read, “He called the twelve together and gave them power and authority over all demons and to cure diseases, and He sent them out to proclaim the kingdom of God and heal.” This is a staggering commission. Jesus was not merely sending them out as passive messengers but directly empowering them with His divine authority.

The text specifies that He gave them “power and authority over all demons and to cure diseases.”  This was no small matter. Demons were understood to be powerful spiritual forces that could torment and possess human beings. Yet Jesus was entrusting His followers with the ability to cast out these unclean spirits and bring healing to the afflicted.

But the disciples’ mission was more than just casting out demons and miraculous healings. Jesus also sent them “to proclaim the kingdom of God” (Luke 9:2). In other words, they were to be authoritative heralds of the new reality that Jesus had inaugurated – the breaking in of God’s reign on earth. This is the “two-hand punch” that every believer must apply in their ministry – applying power and authority to minister healing miracles, casting out demons, and sharing the Gospel.

This theme was further developed in Luke 10, where Jesus commissioned 70 or 72 additional disciples and sent them out in pairs. Once again, the emphasis is on the authority and power they have been given. As Jesus instructed them, “Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you” (Luke 10:19).

The implication is clear – those who faithfully represent Jesus as His authorized messengers will be supernaturally empowered to overcome the forces of darkness. They will have the authority to pronounce judgment on demonic powers and declare the triumph of God’s kingdom.

This is a remarkable trust that Jesus placed in His followers. He was not sending them out as mere cheerleaders or bystanders but as authorized agents of His own divine rule. And this authority and power were not for their own aggrandizement but for the advancement of the Gospel and the liberation of the captives.

The same commission stands for Jesus’ disciples today. We too have been entrusted with the authority of the kingdom, empowered by the Holy Spirit to confront the powers of evil, proclaim the good news, and see God’s reign established in the lives of those we reach. What an awesome privilege and responsibility this is!

May we, like the original disciples, faithfully steward this authority and power for the glory of Christ and the expansion of his kingdom. For the battle is the Lord’s, and the victory is assured.

This truth should fill our hearts with boldness and confidence. No matter how daunting the spiritual battle may seem, we can take courage knowing that Jesus has already secured the ultimate victory. With His authority and power behind us, we can advance the kingdom of God and set the captives free, to the glory of his name.
