Mark 9:14-29
Jesus Releases a Boy after Disciples Fail
A father's mixed cry meets a power the disciples could not hold
At the foot of the mountain scribes are questioning the disciples, and a great multitude is looking on. A father has brought a son who has a dumb spirit that tears him, throws him down, and has often cast him into the fire and into the waters to destroy him. The disciples could not cast it out. Jesus names a faithless generation, asks how long the boy has suffered, and hears the father's plea: if thou canst do any thing, have compassion on us. Jesus answers that all things are possible to him that believeth. The father cries, Lord, I believe; help thou mine unbelief. That sentence is honest trust, not a failed exam.
When Jesus rebukes the spirit, the boy is left as one dead, insomuch that many say he is dead. Jesus takes him by the hand and lifts him up, and he arises. Privately the disciples ask why they could not cast it out. He says, This kind can come forth by nothing, but by prayer. Dependence on the Father is the point, not a stored technique in the worker. Mark is narrating a destructive spirit in this boy. The story does not teach that epilepsy, disability, or mental illness is demonic, and it does not send you to diagnose a neighbor's body as a spiritual failure.
How this should shape us
Bring the child, the crisis, and the faith you cannot polish. Pray instead of performing, and do not treat a medical or psychiatric condition as if this scene had already named its cause.

Where careful interpreters disagreeThe strongest options and their difficulties
Where do careful interpreters differ?
Best judgment: Ancient spirit language and symptoms resembling seizures must not become a diagnosis of epilepsy as demonic. Manuscripts differ on 'and fasting' in 9:29. The father's honest mixed faith is not blamed for the crisis.
