Mark 9:14-29; Matthew 17:14-21
After Jesus had came down from the mountain with His disciples, He saw the scribes were quarrelling with His other disciples.
When the people saw Jesus, they ran to Him. Jesus asked the scribes, “What are you quarrelling at?”
Then a man from the crowd came forward and said, “Teacher, my son has a mute spirit. The devil often throws him into convulsion and he will screams. Then foam will comes out from his mouth and he will gnash his teeth. His body will also becomes stiff. The evil spirit seldom left my son unharmed. I brought my son to your disciples to cast out the demon in him, but your disciples could not do it.”
Jesus answered the man,”O, You of little faith! When will you people start to believe? Bring the boy to Me.”
They brought the boy to Jesus. When the boy saw Jesus, the demonic spirit overcame him and he started to foam in his mouth, gnash his teeth, and became stiff.
Jesus asked the boy’s father, “How long has the boy suffered this?”
The boy’s father replied, “My son had been suffering from this since small. The demon always tries to throw my son into the water or fire so that he could destroy him.”
Jesus said to him, “If you believe, then your son can be healed.”
The boy’s father said, “Lord, I believe. Please take away my doubt and help me to believe.”
Then Jesus rebuked the evil spirit, saying, “Dead and mute spirit, I command you to come out of him now!”
The evil spirit cried out in a loud voice and convulsed the boy violently then he came out of the boy.
The boy became as a dead corpse. But Jesus held the boy up and he was completely well again.
Jesus said to the people, “This type of evil spirits can only come out through persistent praying and fasting.”
After that Jesus and His disciples left the place.
