What Does the Bible Say About Casting Out Demons?
Demonic oppression, spiritual warfare, and deliverance are topics that many believers encounter at some point in their faith journey.
The Bible teaches that Jesus had complete authority over demons and that He gave His followers the same power to cast out evil spirits in His name.
Many people today struggle with spiritual attacks, oppression, or fear of demonic influences, but the Word of God provides guidance, protection, and assurance.
Whether you are seeking deliverance, learning about spiritual authority, or strengthening your faith, these scriptures will equip you with biblical truth.
In this article, we will explore 30 powerful Bible verses about casting out demons, divided into nine key themes that will help you understand Jesus’ authority over evil, the believer’s role in spiritual warfare, and how to walk in victory.
Let’s dive into what the Bible teaches about casting out demons and overcoming spiritual darkness.
The Authority of Jesus Over Demons
The Bible makes it clear that Jesus has absolute authority over demons. Throughout His ministry, He demonstrated power over unclean spirits, commanding them to leave and setting people free from bondage.
Jesus’ authority was recognized by the demons themselves—they trembled before Him, knowing that He was the Son of God with the power to destroy them. This authority was not limited to Jesus alone; He extended it to His disciples and all believers.
Here are five powerful scriptures that highlight Jesus’ authority over demons:
Matthew 8:16
“When evening came, many who were demon-possessed were brought to him, and he drove out the spirits with a word and healed all the sick.”
Luke 4:41
“Moreover, demons came out of many people, shouting, ‘You are the Son of God!’ But he rebuked them and would not allow them to speak, because they knew he was the Messiah.”
Mark 1:34
“And he healed many who were sick with various diseases and drove out many demons. But he would not let the demons speak because they knew who he was.”
Matthew 28:18
“Then Jesus came to them and said, ‘All authority in heaven and on earth has been given to me.'”
Mark 5:8
“For Jesus had said to him, ‘Come out of this man, you impure spirit!'”
These verses confirm that Jesus is sovereign over the spiritual realm, and no demonic force can resist His power. His ability to cast out demons with a single word reveals that darkness has no place in His presence.
The Power Given to Believers to Cast Out Demons
Jesus didn’t just demonstrate authority over demons—He passed that authority to His followers. As believers, we are called to walk in the power of Christ and cast out demons in His name.
The Bible makes it clear that those who have faith in Jesus have been given spiritual authority over evil spirits, strongholds, and demonic oppression. Through faith, prayer, and the power of the Holy Spirit, we can stand firm against the enemy.
Here are five powerful scriptures about the power given to believers to cast out demons:
Mark 16:17
“And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues.”
Luke 10:19
“I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you.”
Acts 16:18
“She kept this up for many days. Finally, Paul became so annoyed that he turned around and said to the spirit, ‘In the name of Jesus Christ I command you to come out of her!’ At that moment the spirit left her.”
Matthew 10:1
“Jesus called his twelve disciples to him and gave them authority to drive out impure spirits and to heal every disease and sickness.”
John 14:12
“Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these, because I am going to the Father.”
These scriptures remind us that we are not powerless against demonic forces. Jesus has equipped us with His authority, and through faith in Him, we can stand against the enemy and walk in victory.
The Role of Faith in Casting Out Demons
Faith is an essential weapon in spiritual warfare. Without faith, believers cannot exercise authority over demons or stand firm against the enemy. Jesus taught that even a small amount of faith can move mountains—including demonic strongholds.
When we trust in God’s power and walk in faith, we activate His supernatural strength in our lives. These verses emphasize the importance of faith when casting out demons.
Matthew 17:20
“He replied, ‘Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.'”
Hebrews 11:6
“And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.”
James 4:7
“Submit yourselves, then, to God. Resist the devil, and he will flee from you.”
2 Corinthians 10:4
“The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.”
Mark 9:23
“‘If you can?’ said Jesus. ‘Everything is possible for one who believes.’”
These verses show that faith is the key to victory over the enemy. When we walk in faith and stand on God’s Word, the forces of darkness cannot prevail against us.
The Importance of Prayer and Fasting in Deliverance
Some spiritual battles require more than just a spoken command—they demand prayer and fasting to break strongholds. Jesus Himself emphasized that some demonic forces will not leave without dedicated prayer and fasting.
Prayer aligns our hearts with God’s will, and fasting deepens our dependence on Him, making us spiritually stronger against the enemy. These practices equip believers with the power to overcome stubborn demonic influences.
Here are five powerful scriptures on the importance of prayer and fasting in deliverance:
Matthew 17:21
“However, this kind does not go out except by prayer and fasting.”
Mark 9:29
“He replied, ‘This kind can come out only by prayer.'”
Isaiah 58:6
“Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke?”
Joel 2:12
“Even now,” declares the Lord, “return to me with all your heart, with fasting and weeping and mourning.”
Acts 13:2-3
“While they were worshiping the Lord and fasting, the Holy Spirit said, ‘Set apart for me Barnabas and Saul for the work to which I have called them.’ So after they had fasted and prayed, they placed their hands on them and sent them off.”
These scriptures remind us that fasting and prayer prepare believers for greater spiritual victories. Through these disciplines, we become more sensitive to the Holy Spirit, enabling us to break free from demonic oppression.
Protection From Evil Spirits and Demonic Attacks
Spiritual attacks are real, but the Bible assures us that God provides protection for His children. When we trust in His Word, walk in obedience, and cover ourselves in prayer, the enemy has no power over us.
God’s promises guarantee divine protection from demonic forces, and His angels guard those who fear Him. These scriptures emphasize God’s power to shield His people from evil.
Ephesians 6:12
“For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.”
Psalm 91:11-12
“For he will command his angels concerning you to guard you in all your ways; they will lift you up in their hands, so that you will not strike your foot against a stone.”
2 Thessalonians 3:3
“But the Lord is faithful, and he will strengthen you and protect you from the evil one.”
1 John 4:4
“You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.”
Colossians 2:15
“And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.”
These verses confirm that believers do not need to live in fear of demonic forces. When we stand on God’s promises and wear the armor of God, we are protected from every attack of the enemy.
Warnings Against Engaging With Evil Spirits
The Bible strongly warns against any form of involvement with the occult, witchcraft, or demonic practices. Engaging in such activities opens doors to demonic oppression and places people under the influence of evil spirits.
Many today unknowingly expose themselves to spiritual attacks by participating in tarot readings, astrology, Ouija boards, and other occult practices. The Bible makes it clear that God detests these things and calls His people to separate themselves from all forms of darkness.
Here are five powerful scriptures warning against engaging with evil spirits:
Deuteronomy 18:10-12
“Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead. Anyone who does these things is detestable to the Lord.”
Leviticus 19:31
“Do not turn to mediums or seek out spiritists, for you will be defiled by them. I am the Lord your God.”
Acts 19:19
“A number who had practiced sorcery brought their scrolls together and burned them publicly. When they calculated the value of the scrolls, the total came to fifty thousand drachmas.”
1 Timothy 4:1
“The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons.”
Galatians 5:19-21
“The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.”
These verses clearly instruct believers to stay away from all occult practices. Instead of seeking guidance from demonic sources, we should turn to God, His Word, and the Holy Spirit for wisdom and direction.
Jesus’ Teachings on Overcoming Satan
Jesus taught that Satan is real, but his power is limited. As followers of Christ, we are called to be spiritually alert, resist the devil, and rely on God’s power to overcome temptation and demonic influences.
Jesus frequently spoke about the reality of spiritual warfare and gave instructions on how believers can defeat the enemy. These verses equip Christians with biblical strategies to resist and overcome Satan.
Luke 11:24-26
“When an impure spirit comes out of a person, it goes through arid places seeking rest and does not find it. Then it says, ‘I will return to the house I left.’ When it arrives, it finds the house swept clean and put in order. Then it goes and takes seven other spirits more wicked than itself, and they go in and live there. And the final condition of that person is worse than the first.”
John 8:44
“You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.”
Matthew 12:28
“But if it is by the Spirit of God that I drive out demons, then the kingdom of God has come upon you.”
1 Peter 5:8-9
“Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.”
Revelation 12:11
“They triumphed over him by the blood of the Lamb and by the word of their testimony; they did not love their lives so much as to shrink from death.”
These verses highlight that Satan is a defeated enemy. By standing firm in faith, resisting temptation, and trusting in the power of Jesus, believers can walk in victory over the forces of darkness.
Victory in Christ Over All Evil Forces
The Bible teaches that Satan and his demons have already been defeated through the work of Jesus Christ. Because of His death and resurrection, believers have been delivered from the power of darkness and now walk in the victory of Christ.
Even though spiritual warfare continues, we do not fight for victory—we fight from victory. Jesus’ triumph on the cross ensures that no demonic force can stand against those who are covered by His blood.
Here are five powerful scriptures that declare victory in Christ over all evil forces:
Romans 16:20
“The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus be with you.”
2 Corinthians 2:14
“But thanks be to God, who always leads us as captives in Christ’s triumphal procession and uses us to spread the aroma of the knowledge of him everywhere.”
1 John 3:8
“The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work.”
Ephesians 1:19-21
“And his incomparably great power for us who believe. That power is the same as the mighty strength he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms, far above all rule and authority, power and dominion, and every name that is invoked, not only in the present age but also in the one to come.”
Colossians 1:13
“For he has rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves.”
These scriptures affirm that Christ’s victory over Satan is final. No matter how intense spiritual warfare may seem, we can stand in faith knowing that God has already won the battle.
FAQs About Casting Out Demons
To provide additional clarity and address common concerns, here are some frequently asked questions about casting out demons and spiritual warfare.
1. Can all believers cast out demons?
Yes, all true believers in Jesus Christ have authority over demons. Jesus gave His disciples the power to cast out unclean spirits (Mark 16:17, Luke 10:19), and that authority extends to all who follow Him in faith. However, effective deliverance requires faith, prayer, and spiritual discernment.
2. Why do some demons resist being cast out?
Some demons are more deeply rooted due to legal rights (such as unrepented sin, generational curses, or occult involvement). Jesus taught that some spirits require prayer and fasting for removal (Mark 9:29). Persistence in faith, fasting, and seeking God’s guidance is necessary in difficult cases.
3. What are the signs of demonic oppression?
Demonic oppression can manifest in different ways, including:
- Unexplainable fear, anxiety, or depression
- Persistent sinful struggles that resist repentance
- Hearing voices, seeing disturbing visions, or unnatural thoughts
- Strong resistance to prayer, worship, or reading the Bible
- Physical sensations, sleep paralysis, or unexplained illnesses
Not all difficulties are demonic in nature, so discernment and prayer are needed to determine if deliverance is required.
4. How can I protect myself from demonic attacks?
Believers can protect themselves through:
- Daily prayer and seeking God’s presence (James 4:7)
- Reading and meditating on Scripture (Ephesians 6:17)

- Avoiding sinful and occult influences (Deuteronomy 18:10-12)
- Pleading the blood of Jesus over yourself and your household (Revelation 12:11)
5. Can demons possess Christians?
No, a true born-again believer cannot be possessed because the Holy Spirit dwells within them (1 Corinthians 6:19). However, Christians can be oppressed or attacked if they allow sin, fear, or doubt to weaken their spiritual defenses. Deliverance may be needed to break strongholds and regain spiritual freedom.
6. How do I cast out a demon?
Casting out demons requires:
- Faith in Jesus Christ – Only through His name can demons be cast out (Mark 16:17).
- Repentance & Confession – Closing any spiritual doors that allow demonic influence.
- Commanding the demon to leave – Using the authority of Jesus to rebuke the evil spirit.
- Filling the person with God’s Word & Spirit – Ensuring they are spiritually strengthened so demons cannot return (Luke 11:24-26).
If you are new to deliverance, seek spiritual guidance from mature believers or church leaders.
7. What should I do after deliverance?
After deliverance, it is important to:
- Stay connected to God through prayer and Bible study
- Surround yourself with other believers for accountability
- Remove any objects or influences that could invite demonic oppression
- Continue to walk in obedience to God’s Word
Jesus warned that if a person does not stay spiritually strong, demons can return in greater force (Luke 11:24-26).
8. Are exorcisms only performed by priests or pastors?
No, any believer in Jesus Christ can cast out demons. However, spiritual maturity and understanding are important. While some churches have trained pastors for deliverance, the authority to cast out demons is given to all true followers of Christ (Mark 16:17).
