6 Bible Verses about Demons Causing Illness

And someone in the crowd answered Him, "Teacher, I brought to you my son, who is dominated by a spirit which causes him to be a mute. Wherever it seizes him, it throws him down and he foams at the mouth, grinds his teeth and stiffens out. I spoke to your disciples, asking them to drive it out, but they were not able to." Jesus said to them, "You generation of faithless people How long must I be with you [i.e., before you understand]? How long do I have to be patient with you? Bring the sick boy to me."read more.
Then they [i.e., some people from the crowd] brought the sick boy to Jesus, and when the spirit saw Him, it immediately caused the boy to have convulsions and to fall to the ground and roll around, foaming at the mouth. Jesus asked the boy's father, "How long has this been happening to him?" And he answered, "Since he was a small child. And frequently the evil spirit has tried to kill him, throwing him into a fire or into the water. But if you can do anything [for him], have pity on us and help us." And Jesus said to him, "'If you can.' [Note: By repeating the man's words Jesus seems to be saying, "You mean, if YOU can believe"]. Everything is possible to the person who believes [it can happen]." Immediately the father of the boy cried out, "I do believe; help me to have more faith." When Jesus saw a crowd running together [toward Him], He spoke sternly to the evil spirit [in the boy], saying to it, "You deaf-mute spirit, I order you to come out of this boy and to never return to him again." The spirit shrieked and caused violent convulsions [in the boy], then came out of him. The boy appeared to be dead, so that most of the people were saying, "He is dead." But Jesus grasped his hand and lifted him up, and he arose [fully healed].

When Jesus and His disciples met the crowd [that was gathered], a man came kneeling down to Jesus and saying to Him, "Lord, take pity on my son, for he has violent seizures and suffers intense pain. He often falls into a fire or into water. [Note: This man was also dominated by an evil spirit. See verse 18]. I brought him to [some of] your disciples [for help] but they were not able to heal him."read more.
Jesus replied [to the crowd], "You perverse generation of faithless people! How long must I be with you [i.e., before you understand]? How long do I have to be patient with you? Bring the sick boy to me." Then Jesus spoke sternly to [the evil spirit in] the boy, and it left him, and he was immediately healed.

And it happened on the next day, when they had come down from the mountain, that a large crowd met Jesus. Just then a man from the crowd shouted out, "Teacher, I beg you, look at my son [i.e., favorably], for he is my only child. For when an evil spirit takes hold of him he suddenly screams and [then] it throws him into convulsions so that he foams [at the mouth]. And it does not want to leave him, [even after] severely bruising him.read more.
And I begged your disciples to drive it out, but they could not." And Jesus replied, saying, "You perverse generation of faithless people! How long must I be [patient] with you, and put up with you [i.e., before you understand]? Bring your son here." And while the boy was approaching [Jesus], an evil spirit threw him to the ground in a convulsion. But Jesus spoke sternly to the evil spirit and [then] returned him to his father healed.

As they went on their way a deaf-mute, dominated by an evil spirit, was brought to Jesus. When the evil spirit was driven out [by Jesus] the [former] deaf-mute began to speak, and the crowds marveled, saying, "No one in Israel has ever seen this done before."

[Once] Jesus was driving out an evil spirit from a [man who was] mute. And it happened when the evil spirit left [him] that the [former] mute began to speak. And the crowds were amazed.

And just then [He met] a woman who had an [evil] spirit that had caused her to be deformed for eighteen years. She was bent over and could not raise herself up. [Note: This was probably osteomyelitis or osteoporosis].
