Mark 9:33-40

33They came to Capernaum. When he was in the house, he asked them, “What were you arguing about on the way?”

34But they were silent, because on the way they had been arguing with one another about who was the greatest.

35Sitting down, he called the Twelve and said to them, “If anyone wants to be first, he must be last and servant of all.”

36He took a child, had him stand among them, and taking him in his arms, he said to them,

37“Whoever welcomes one little child such as this in my name welcomes me. And whoever welcomes me does not welcome me, but him who sent me.”

38John said to him, “Teacher, we saw someone driving out demons in your name, and we tried to stop him because he wasn’t following us.”

39“Don’t stop him,” said Jesus, “because there is no one who will perform a miracle in my name who can soon afterward speak evil of me.

40For whoever is not against us is for us.
