14 When they returned to the other disciples, they saw a large crowd around them, and scribes arguing with them.
15 As soon as all the people saw Jesus, they were filled with awe and ran to greet Him.
16 “What are you disputing with them?” He asked.
17 Someone in the crowd replied, “Teacher, I brought You my son, who has a spirit that makes him mute.
18 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 it out, but they were unable.”
19 “O unbelieving generation!” Jesus replied. “How long must I remain with you? How long must I put up with you? Bring the boy to Me.”
20 So 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.
21 Jesus 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.”
23 “If You can?” echoed Jesus. “All things are possible to him who believes!”
24 Immediately the boy’s father cried out, “I do believe; help my unbelief!”
25 When Jesus saw that a crowd had come running, He rebuked the unclean spirit. “You deaf and mute spirit,” He said, “I command you to come out and never enter him again.”
26 After shrieking and convulsing him violently, the spirit came out. The boy became like a corpse, so that many said, “He is dead.”
27 But Jesus took him by the hand and helped him to his feet, and he stood up.
28 After Jesus had gone into the house, His disciples asked Him privately, “Why couldn’t we drive it out?”
29 Jesus answered, “This kind cannot come out, except by prayer.”
