17 A man in the crowd answered, “Teacher, I brought my son to you, because he has an evil spirit in him and cannot talk.
18 Whenever the spirit attacks him, it throws him to the ground, and he foams at the mouth, grits his teeth, and becomes stiff all over. I asked your disciples to drive the spirit out, but they could not.”
19 Jesus said to them, “How unbelieving you people are! How long must I stay with you? How long do I have to put up with you? Bring the boy to me!”
20 They brought him to Jesus.As soon as the spirit saw Jesus, it threw the boy into a fit, so that he fell on the ground and rolled around, foaming at the mouth.
21 “How long has he been like this?” Jesus asked the father.“Ever since he was a child,” he replied.
22 “Many times the evil spirit has tried to kill him by throwing him in the fire and into water. Have pity on us and help us, if you possibly can!”
23 “Yes,” said Jesus, “if you yourself can! Everything is possible for the person who has faith.”
