Dealing with demonic powers is not something to be left to professional ministers. Jesus said all believers would have the ability to overcome demonic powers:
"And these signs shall follow them that believe: In my name shall they cast out devils..."--Mark 16:17
Jesus gave His followers the ability to deal with demonic powers. He first delegated such power to the disciples:
"And when He had called unto Him His twelve disciples, He gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease." --Matthew 10:1
"And He called unto Him the twelve, and began to send them forth by two and two; and gave them power over unclean spirits." --Mark 6:7
He delegated this same power to all believers:
"And these signs shall follow them that believe: In my name shall they cast out devils..." --Mark 16:17
"Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give." --Matthew 10:8
There is no Biblical basis for believing God intended this important ministry to be restricted to a particular group of people.
This does not mean believers should rush into encounters with demonic powers without proper preparation, as the sons of Sceva discovered (Acts 19). It is also important that believers do not become overly demon conscious. We are not called to major in demons. There is no spiritual gift of "casting out demons." But you are not to fear demonic powers. When confronted with those affected by demons, you should have the power to bring deliverance from God.
Unbelief hindered even the ministry of Jesus in Nazareth. Sometimes Jesus put unbelievers out when He ministered:
Mark 5:35-40:
35 "While he yet spake, there came from the ruler of the synagogue's house certain which said, Thy daughter is dead: why troublest thou the Master any further?
36 As soon as Jesus heard the word that was spoken, he saith unto the ruler of the synagogue, Be not afraid, only believe.
37 And he suffered no man to follow him, save Peter, and James, and John the brother of James.
38 And he cometh to the house of the ruler of the synagogue, and seeth the tumult, and them that wept and wailed greatly.
39 And when he was come in, he saith unto them, Why make ye this ado, and weep? the damsel is not dead, but sleepeth.
40 And they laughed him to scorn. But when he had put them all out, he taketh the father and the mother of the damsel, and them that were with him, and entereth in where the damsel was lying."
Other times He led people out of their village (an environment of unbelief) in order to minister to them:
Mark 8:23:
"And he took the blind man by the hand, and led him out of the town; and when he had spit on his eyes, and put his hands upon him, he asked him if he saw ought."
On occasion as God leads, you may need to ask those struggling with unbelief, fear, etc., to leave.
Here are Biblical references to how Jesus dealt with conditions caused by demonic influence:
Crippled woman:
Luke 13:10-17:
10 "And he was teaching in one of the synagogues on the sabbath.
11 "And, behold, there was a woman which had a spirit of infirmity eighteen years, and was bowed together, and could in no wise lift up herself.
12 "And when Jesus saw her, he called her to him, and said unto her, Woman, thou art loosed from thine infirmity.
13 "And he laid his hands on her: and immediately she was made straight, and glorified God.
14 "And the ruler of the synagogue answered with indignation, because that Jesus had healed on the sabbath day, and said unto the people, There are six days in which men ought to work: in them therefore come and be healed, and not on the sabbath day.
15 "The Lord then answered him, and said, Thou hypocrite, doth not each one of you on the sabbath loose his ox or his ass from the stall, and lead him away to watering?
16 "And ought not this woman, being a daughter of Abraham, whom Satan hath bound, lo, these eighteen years, be loosed from this bond on the sabbath day?
17 "And when he had said these things, all his adversaries were ashamed: and all the people rejoiced for all the glorious things that were done by him."
Man with unclean spirit in the synagogue:
Mark 1:23-28:
23 "And there was in their synagogue a man with an unclean spirit; and he cried out,
24 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art, the Holy One of God.
25 And Jesus rebuked him, saying, Hold thy peace, and come out of him.
26 And when the unclean spirit had torn him, and cried with a loud voice, he came out of him.
27 And they were all amazed, insomuch that they questioned among themselves, saying, What thing is this? what new doctrine is this? for with authority commandeth he even the unclean spirits, and they do obey him.
28 And immediately his fame spread abroad throughout all the region round about Galilee."
Luke 4:31-37:
31 "And came down to Capernaum, a city of Galilee, and taught them on the sabbath days.
32 And they were astonished at his doctrine: for his word was with power.
33 And in the synagogue there was a man, which had a spirit of an unclean devil, and cried out with a loud voice,
34 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art; the Holy One of God.
35 And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the devil had thrown him in the midst, he came out of him, and hurt him not.
36 And they were all amazed, and spake among themselves, saying, What a word is this! for with authority and power he commandeth the unclean spirits, and they come out.
37 And the fame of him went out into every place of the country round about."
Gadarene demoniac:
Matthew 8:28-32:
28 And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way.
29 And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?
30 And there was a good way off from them an herd of many swine feeding.
31 So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine.
32 And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters."
Mark 5:1-13:
1 "And they came over unto the other side of the sea, into the country of the Gadarenes.
2 And when he was come out of the ship, immediately there met him out of the tombs a man with an unclean spirit,
3 Who had his dwelling among the tombs; and no man could bind him, no, not with chains:
4 Because that he had been often bound with fetters and chains, and the chains had been plucked asunder by him, and the fetters broken in pieces: neither could any man tame him.
5 And always, night and day, he was in the mountains, and in the tombs, crying, and cutting himself with stones.
6 But when he saw Jesus afar off, he ran and worshipped him,
7 And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not.
8 For he said unto him, Come out of the man, thou unclean spirit.
9 And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many.
10 And he besought him much that he would not send them away out of the country.
11 Now there was there nigh unto the mountains a great herd of swine feeding.
12 And all the devils besought him, saying, Send us into the swine, that we may enter into them.
13 And forthwith Jesus gave them leave. And the unclean spirits went out, and entered into the swine: and the herd ran violently down a steep place into the sea, (they were about two thousand;) and were choked in the sea."
Luke 8:26-33:
26 "And they arrived at the country of the Gadarenes, which is over against Galilee.
27 And when he went forth to land, there met him out of the city a certain man, which had devils long time, and ware no clothes, neither abode in any house, but in the tombs.
28 When he saw Jesus, he cried out, and fell down before him, and with a loud voice said, What have I to do with thee, Jesus, thou Son of God most high? I beseech thee, torment me not.
29 (For he had commanded the unclean spirit to come out of the man. For oftentimes it had caught him: and he was kept bound with chains and in fetters; and he brake the bands, and was driven of the devil into the wilderness.)
30 And Jesus asked him, saying, What is thy name? And he said, Legion: because many devils were entered into him.
31 And they besought him that he would not command them to go out into the deep.
32 And there was there an herd of many swine feeding on the mountain: and they besought him that he would suffer them to enter into them. And he suffered them.
33 Then went the devils out of the man, and entered into the swine: and the herd ran violently down a steep place into the lake, and were choked."
Woman with issue of blood:
Matthew 9:20-23:
20 "And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment:
21 For she said within herself, If I may but touch his garment, I shall be whole.
22 But Jesus turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour.
23 And when Jesus came into the ruler's house, and saw the minstrels and the people making a noise,"
Mark 5:25-34:
25 "And a certain woman, which had an issue of blood twelve years,
26 And had suffered many things of many physicians, and had spent all that she had, and was nothing bettered, but rather grew worse,
27 When she had heard of Jesus, came in the press behind, and touched his garment.
28 For she said, If I may touch but his clothes, I shall be whole.
29 And straightway the fountain of her blood was dried up; and she felt in her body that she was healed of that plague.
30 And Jesus, immediately knowing in himself that virtue had gone out of him, turned him about in the press, and said, Who touched my clothes?
31 And his disciples said unto him, Thou seest the multitude thronging thee, and sayest thou, Who touched me?
32 And he looked round about to see her that had done this thing.
33 But the woman fearing and trembling, knowing what was done in her, came and fell down before him, and told him all the truth.
34 And he said unto her, Daughter, thy faith hath made thee whole; go in peace, and be whole of thy plague."
Luke 8:43-48:
43 "And a woman having an issue of blood twelve years, which had spent all her living upon physicians, neither could be healed of any,
44 Came behind him, and touched the border of his garment: and immediately her issue of blood stanched.
45 And Jesus said, Who touched me? When all denied, Peter and they that were with him said, Master, the multitude throng thee and press thee, and sayest thou, Who touched me?
46 And Jesus said, Somebody hath touched me: for I perceive that virtue is gone out of me.
47 And when the woman saw that she was not hid, she came trembling, and falling down before him, she declared unto him before all the people for what cause she had touched him, and how she was healed immediately.
48 And he said unto her, Daughter, be of good comfort: thy faith hath made thee whole; go in peace."
Syro-phoenician's daughter:
Matthew 15:21-28:
21 "Then Jesus went thence, and departed into the coasts of Tyre and Sidon.
22 And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou son of David; my daughter is grievously vexed with a devil.
23 But he answered her not a word. And his disciples came and besought him, saying, Send her away; for she crieth after us.
24 But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
25 Then came she and worshipped him, saying, Lord, help me.
26 But he answered and said, It is not meet to take the children's bread, and to cast it to dogs.
27 And she said, Truth, Lord: yet the dogs eat of the crumbs which fall from their masters' table.
28 Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour."
Mark 7:24-30:
24 "And from thence he arose, and went into the borders of Tyre and Sidon, and entered into an house, and would have no man know it: but he could not be hid.
25 For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet:
26 The woman was a Greek, a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter.
27 But Jesus said unto her, Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs.
28 And she answered and said unto him, Yes, Lord: yet the dogs under the table eat of the children's crumbs.
29 And he said unto her, For this saying go thy way; the devil is gone out of thy daughter.
30 And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed."
Child with evil spirit:
Matthew 17:14-21:
14 "And when they were come to the multitude, there came to him a certain man, kneeling down to him, and saying,
15 Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.
16 And I brought him to thy disciples, and they could not cure him.
17 Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me.
18 And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour.
19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?
20 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
21 Howbeit this kind goeth not out but by prayer and fasting."
Mark 9:14-29:
14 "And when he came to his disciples, he saw a great multitude about them, and the scribes questioning with them.
15 And straightway all the people, when they beheld him, were greatly amazed, and running to him saluted him.
16 And he asked the scribes, What question ye with them?
17 And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit;
18 And wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out; and they could not.
19 He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.
20 And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.
21 And he asked his father, How long is it ago since this came unto him? And he said, Of a child.
22 And ofttimes it hath cast him into the fire, and into the waters, to destroy him: but if thou canst do any thing, have compassion on us, and help us.
23 Jesus said unto him, If thou canst believe, all things are possible to him that believeth.
24 And straightway the father of the child cried out, and said with tears, Lord, I believe; help thou mine unbelief.
25 When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.
26 And the spirit cried, and rent him sore, and came out of him: and he was as one dead; insomuch that many said, He is dead.
27 But Jesus took him by the hand, and lifted him up; and he arose.
28 And when he was come into the house, his disciples asked him privately, Why could not we cast him out?
29 And he said unto them, This kind can come forth by nothing, but by prayer and fasting."
Luke 9:37-45:
37 "And it came to pass, that on the next day, when they were come down from the hill, much people met him.
38 And, behold, a man of the company cried out, saying, Master, I beseech thee, look upon my son: for he is mine only child.
39 And, lo, a spirit taketh him, and he suddenly crieth out; and it teareth him that he foameth again, and bruising him hardly departeth from him.
40 And I besought thy disciples to cast him out; and they could not.
41 And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither.
42 And as he was yet a coming, the devil threw him down, and tare him. And Jesus rebuked the unclean spirit, and healed the child, and delivered him again to his father.
43 And they were all amazed at the mighty power of God. But while they wondered every one at all things which Jesus did, he said unto his disciples,
44 Let these sayings sink down into your ears: for the Son of man shall be delivered into the hands of men.
45 But they understood not this saying, and it was hid from them, that they perceived it not: and they feared to ask him of that saying."
Dumb demoniac:
Matthew 9:32-33:
32 "As they went out, behold, they brought to him a dumb man possessed with a devil.
33 And when the devil was cast out, the dumb spake: and the multitudes marvelled, saying, It was never so seen in Israel."
Blind and dumb demoniac:
Matthew 12:22-30:
22 "Then was brought unto him one possessed with a devil, blind, and dumb: and he healed him, insomuch that the blind and dumb both spake and saw.
23 And all the people were amazed, and said, Is not this the son of David?
24 But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
25 And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:
26 And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand?
27 And if I by Beelzebub cast out devils, by whom do your children cast them out? therefore they shall be your judges.
28 But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.
29 Or else how can one enter into a strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house.
30 He that is not with me is against me; and he that gathereth not with me scattereth abroad."
Mark 3:22-27:
22 "And the scribes which came down from Jerusalem said, He hath Beelzebub, and by the prince of the devils casteth he out devils.
23 And he called them unto him, and said unto them in parables, How can Satan cast out Satan?
24 And if a kingdom be divided against itself, that kingdom cannot stand.
25 And if a house be divided against itself, that house cannot stand.
26 And if Satan rise up against himself, and be divided, he cannot stand, but hath an end.
27 No man can enter into a strong man's house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house."
Luke 11:14-26:
14 "And he was casting out a devil, and it was dumb. And it came to pass, when the devil was gone out, the dumb spake; and the people wondered.
15 But some of them said, He casteth out devils through Beelzebub the chief of the devils.
16 And others, tempting him, sought of him a sign from heaven.
17 But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth.
18 If Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub.
19 And if I by Beelzebub cast out devils, by whom do your sons cast them out? therefore shall they be your judges.
20 But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you.
21 When a strong man armed keepeth his palace, his goods are in peace:
22 But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armour wherein he trusted, and divideth his spoils.
23 He that is not with me is against me: and he that gathereth not with me scattereth.
24 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.
25 And when he cometh, he findeth it swept and garnished.
26 Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first."
Other incidents: In addition to these specific encounters of Jesus, the Bible makes general references of His ministry to those affected by demonic powers:
- In the following references the term "healed" is used to describe how Jesus dealt with the demons:
Matthew 4:24:
"And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them."
Luke 6:18:
"And they that were vexed with unclean spirits: and they were healed."
- In the following references the term "cast out" is used to describe His strategy:
Mark 1:32-34,39:
32 "And at even, when the sun did set, they brought unto him all that were diseased, and them that were possessed with devils.
33 And all the city was gathered together at the door.
34 And he healed many that were sick of divers diseases, and cast out many devils; and suffered not the devils to speak, because they knew him.
39 And he preached in their synagogues throughout all Galilee, and cast out devils."
Mark 6:13:
"And they cast out many devils, and anointed with oil many that were sick, and healed them."
- Luke 4:41 simply records that the devils "came out." Luke 7:21 states that He "cured" them. Matthew 8:16 records that He "cast them out with His Word." Mark 16:9 and Luke 8:2-3 state that Jesus cast seven devils out of Mary Magdalene.
In large crowds, Jesus did not allow the demons to speak out:
Mark 1:32-34:
32 "And at even, when the sun did set, they brought unto him all that were diseased, and them that were possessed with devils.
33 And all the city was gathered together at the door.
34 And he healed many that were sick of divers diseases, and cast out many devils; and suffered not the devils to speak, because they knew him."
