Mark 9:17-18, 20, 22-24

A man in the crowd answered, “Teacher, I brought you my son, who is possessed by a spirit that has robbed him of speech. Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth and becomes rigid. I asked your disciples to drive out the spirit, but they could not.”

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

“It has often thrown him into fire or water to kill him. But if you can do anything, take pity on us and help us.” “ ‘If you can’?” said Jesus. “Everything is possible for one who believes.” Immediately the boy’s father exclaimed, “I do believe; help me overcome my unbelief!”
