and said, "Father, have mercy on my son. He was sick epilepsy and attack so powerful that he often falls into the fire and often into the water.
I've brought him to the your followers, but they can not cure him. "
Jesus replied, You're really the people who do not believe. Until when I have to stay with you and be patient with you? Bring the boy here!"
Then Jesus commanded the evil spirit in the boy out. And the evil spirit out, then the child was healed at that moment.

Jesus answered, "Because you less believe. Remember! If you have great faith a size mustard seed you can say to this mountain, 'Move on there!" surely this hill will move. everything you can make!
(But this kind of evil spirit, can only be driven out by prayer and fasting only.) "
