Mark 9:20

One of the multitude answered, “Teacher, I brought to you my son, who has a mute spirit;

and wherever it seizes him, it throws him down; and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, and they weren’t able.”

He answered him, “Unbelieving generation, how long shall I be with you? How long shall I bear with you? Bring him to me.”

He asked his father, “How long has it been since this has been happening to him?”

He said, “From childhood.

Often it has cast him both into the fire and into the water to destroy him. But if you can do anything, have compassion on us and help us.”

Jesus said to him, “If you can believe, all things are possible to him who believes.”
