Mark 9:13-23

13 But I tell you, that Elijah has come, and they have also done to him whatever they wanted to, even as it is written about him."
14 Coming to the disciples, he saw a great multitude around them, and scribes questioning them.
15 Immediately all the multitude, when they saw him, were greatly amazed, and running to him greeted him.
16 He asked the scribes, "What are you asking them?"
17 One of the multitude answered, "Teacher, I brought to you my son, who has a mute spirit;
18 and wherever it seizes him, it dashes him down, and he foams at the mouth, and grinds his teeth, and wastes away. I asked your disciples to cast it out, and they weren't able."
19 He answered him, "Unbelieving generation, how long will I be with you? How long will I bear with you? Bring him to me."
20 They brought him to him, and when he saw him, immediately the spirit convulsed him, and he fell on the ground, wallowing and foaming at the mouth.
21 He asked his father, "How long has it been since this has come to him?" He said, "From childhood.
22 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."
23 Jesus said to him, "If you can believe? All things are possible to him who believes."
