“Chapter 34: The Boy with an Evil Spirit,” New Testament Stories (2005), 80–81
One day a man asked the Savior to help his son. The boy had an evil spirit in him. The disciples had already tried to heal his son, but they could not.
Jesus had the man bring his son to Him. When the boy came, the evil spirit made him fall to the ground.
The Savior asked how long the evil spirit had been in the boy. The father said that it had been in him since he was a child.
Jesus said that He could heal the son if the father had faith. The father began to cry. He said that he had faith. But he asked Jesus to help him have even more faith.
Jesus commanded the evil spirit to come out of the boy and never go into him again. The evil spirit was angry. It hurt the boy again. Then it obeyed Jesus and left.
The boy was so quiet that many people said he was dead. But Jesus took his hand and helped him stand up. The boy was healed. The evil spirit was gone.
Later the disciples asked Jesus why they had not been able to make the evil spirit leave the boy. Jesus told them that sometimes they needed to fast and pray in order for a person to be healed.
