Mark 9:20-22

20So they brought him, and seeing Jesus, the spirit immediately threw the boy into a convulsion. He fell to the ground and rolled around, foaming at the mouth.

21Jesus asked the boy’s father, “How long has this been with him?”

“From childhood,” he said. 22“It often throws him into the fire or into the water, trying to kill him. But if You can do anything, have compassion on us and help us.”
