Scripture Reading: Matthew 8:28-34
Key Verse(s): They began screaming at him, "Why are you bothering us, Son of God? You have no right to torture us before God's appointed time!" (Matthew 8:29)
Demons are fallen angels who serve Satan.
Demon-possessed people are under the control of one or more demons. Demons are fallen angels who joined Satan in his rebellion against God and are now evil spirits under Satan's control. They help Satan tempt people to sin and have great destructive powers. But whenever they are confronted by Jesus, they lose their power.
These demons recognized Jesus as God's Son, but they didn't think they had to obey him. Just believing is not enough (see James 2:19 for a discussion of belief and devils). Faith is more than belief. By faith, you accept what Jesus has done for you, receive him as the only one who can save you from sin, and live out your faith by obeying his commands.
The fate of demons is sealed.
The Bible tells us that at the end of the world the devil and his angels will be thrown into the lake of burning sulfur (Revelation 20:10). When the demons asked if Jesus had come to torment them "before God's appointed time," they showed they knew their ultimate fate.
The goal of demons is destruction.
When the demons entered the pigs, they drove the animals into the sea. The demons' action proves their destructive intent--if they could not destroy the men, they would destroy the pigs. Jesus' action, by contrast, shows the value he places on each human life.
Scripture Reading: Mark 1:21-28
Key Verse(s): Amazement gripped the audience, and they began to discuss what had happened. "What sort of new teaching is this?" they asked excitedly. "It has such authority! Even evil spirits obey his orders!" (Mark 1:27)
Demons are powerful, but limited.
Evil spirits, or demons, are ruled by Satan. They work to tempt people to sin. They were not created by Satan--because God is the Creator of all. Rather they are fallen angels who joined Satan in his rebellion. Though not all disease comes from Satan, demons can cause a person to become mute, deaf, blind, or insane. But in every case where demons confronted Jesus, they lost their power. Thus God limits what evil spirits can do; they can do nothing without his permission. During Jesus' life on earth, demons were allowed to be very active to demonstrate once and for all Christ's power and authority over them.
Demon possession can be similar to mental illness.
Many psychologists dismiss all accounts of demon possession as a primitive way to describe mental illness. Although throughout history mental illness has often been wrongly diagnosed as demon possession, clearly a hostile outside force controlled the man described in Mark 1. Mark emphasized Jesus' conflict with evil powers to show his superiority over them, so he recorded many stories about Jesus driving out evil spirits. Jesus didn't have to conduct an elaborate exorcism ritual. His word was enough to send out the demons. How did Jesus confront demons?
Scripture Reading: Mark 3:7-12
Key Verse(s): Whenever those possessed by evil spirits caught sight of him, they would fall down in front of him shrieking, "You are the Son of God!" (Mark 3:11)
Jesus confronted demons without compromise.
The evil spirits knew that Jesus was the Son of God, but they refused to turn from their evil purposes. Knowing about Jesus, or even believing that he is God's Son, does not guarantee salvation. You must also want to follow and obey him (see James 2:17).
Jesus warned the evil spirits not to reveal his identity as Messiah because he did not want them to reinforce a popular misconception. The huge crowds were looking for a political and military leader who would free them from Rome's control, and they thought that the Messiah predicted by the Old Testament prophets would be this kind of man. Jesus wanted to teach the people about the kind of Messiah he really was--one who was far different from their expectations. Christ's kingdom is spiritual. It begins not with the overthrow of governments, but with the overthrow of sin in a person's heart.
Scripture Reading: Luke 8:26-39
Key Verse(s): "What is your name?" Jesus asked. "Legion," he replied--for the man was filled with many demons. (Luke 8:30)
Jesus confronted demons with absolute authority.
These demons recognized Jesus and his authority immediately. They knew who Jesus was and what his great power could do to them. Demons, Satan's messengers, are powerful and destructive. Still active today, they attempt to distort and destroy people's relationship with God. Demons and demon possession are real. It is vital that believers recognize the power of Satan and his demons, but we shouldn't let curiosity lead us to get involved with demonic forces (Deuteronomy 18:10-12). Demons are powerless against those who trust in Jesus. If we resist the devil, he will leave us alone (James 4:7).
Scripture Reading: Luke 9:37-45
Key Verse(s): As the boy came forward, the demon knocked him to the ground and threw him into a violent convulsion. But Jesus rebuked the evil spirit and healed the boy. Then he gave him back to his father. (Luke 9:42)
Jesus' authority over the demonic continues today.
As the disciples came down from the mountain with Jesus following the transfiguration, they passed from a reassuring experience of God's presence to a frightening experience of evil. The beauty they had just seen must have made the ugliness seem even uglier. As our spiritual vision improves and allows us to see and understand God better, we will also be able to see and understand evil better. We would be overcome by its horror if we did not have Jesus with us to take us through it safely. How are demons present today?
Scripture Reading: Ephesians 6:10-18
Key Verse(s): We are not fighting against people made of flesh and blood, but against the evil rulers and authorities of the unseen world, against those mighty powers of darkness who rule this world, and against wicked spirits in the heavenly realms. (Ephesians 6:12)
The enemy is unseen, but the battle is real.
In the Christian life we battle against rulers and authorities (the powerful evil forces of fallen angels headed by Satan, who is a vicious fighter; see 1 Peter 5:8). To withstand their attacks, we must depend on God's strength and use every piece of his armor. Paul is not only giving this counsel to the church as a whole, but to all individuals within the church. The whole body needs to be armed. As you do battle against "the powers of of darkness who rule this world," fight in the strength of the body of Christ--and remember, its power comes from the Holy Spirit.
The enemy is unseen, but the struggle is personal.
These enemies who are not "flesh and blood" are demons over whom Satan has control. They are not mere fantasies--they are very real. We face a powerful army whose goal is to defeat Christ's church. When we believe in Christ, these beings become our enemies, and they try every device to turn us away from him and back to sin. Although we are assured of victory, we must engage in the struggle until Christ returns because Satan is constantly battling against all who are on the Lord's side. We need supernatural power to defeat Satan, and God has provided this by giving us his Holy Spirit within us and his armor surrounding us. If you feel discouraged, remember Jesus' words to Peter: "Upon this rock I will build my church, and the powers of hell will not conquer it" (Matthew 16:18).
