Jesus answered, "You unbelieving and corrupt generation! How long must I be with you and put up with you? Bring your son here!"
While he was coming [to Jesus], the demon knocked the boy to the ground and threw him into convulsions. Jesus ordered the evil spirit to leave. He cured the boy and gave him back to his father.
Everyone was amazed to see God's wonderful power. Everyone was amazed at all the things that Jesus was doing. So he said to his disciples,
"Listen carefully to what I say. The Son of Man will be betrayed and handed over to people."
They didn't know what he meant. The meaning was hidden from them so that they didn't understand it. Besides, they were afraid to ask him about what he had said.
A discussion started among them about who would be the greatest.
Jesus knew what they were thinking. So he took a little child and had him stand beside him.
Then he said to them, "Whoever welcomes this little child in my name welcomes me. Whoever welcomes me welcomes the one who sent me. The one who is least among all of you is the one who is greatest."
John replied, "Master, we saw someone forcing demons out of a person by using the power and authority of your name. We tried to stop him because he was not one of us."
Jesus said to him, "Don't stop him! Whoever isn't against you is for you."
The time was coming closer for Jesus to be taken to heaven. So he was determined to go to Jerusalem.
