One of the often mistakenly taught passages of Scripture involves Matthew 17 and Mark 9.
We are often told that there are “kinds” of demons that can only be cast out by fasting and praying.
If you look at the text the words “this kind” in his reference to demons refers to this generation.
from 1096; “kin” (abstract or concrete, literal or figurative, individual or collective):–born, country(-man), diversity, generation, kind(-red), nation, offspring, stock.
If you look at the context of Mark 9 Jesus said that “anything is possible for he who believes.”
So fasting and praying has nothing to do with casting of spirits. It is faith that matters.
So what was Jesus referring to when he spoke about “fasting and praying”.
Let’s look at the context.
14 When they came to the other disciples, they saw a large crowd around them and the teachers of the law arguing with them.
No. 1 the disciples were arguing with the teachers of the Law.
19 ‘You unbelieving generation,’ Jesus replied, ‘how long shall I stay with you? How long shall I put up with you? Bring the boy to me.’
No. 2. Jesus said the reason they couldn’t do it was because they had belong to a particular generation and the generation he was referring to was an unbelieving generation
23 ” If you can? ” said Jesus. ‘Everything is possible for one who believes.’
24 Immediately the boy’s father exclaimed, ‘I do believe; help me overcome my unbelief!’
25 When Jesus saw that a crowd was running to the scene, he rebuked the evil spirit. ‘You deaf and mute spirit,’ he said, ‘I command you, come out of him and never enter him again.’
No. 3 Jesus rebuked the spirit without fasting and praying.
As such it is important for us to realise that the disciples had tried to cast the spirit out by the Old Covenant way. Jesus did it through the Spirit.
So when Jesus said to the disciples you can cast it out by fasting and praying, he was referring to:
A) casting out spirits by the old covenant way; and/or
B) the spirit that need to be cast out is the old covenant mentality that they have.
It has nothing to do with fasting and praying to cast out spirits. The name of Jesus suffices.
May that help you.
