Mark 9:35-40

35Sitting down, Jesus called the Twelve and said, “Anyone who wants to be first must be the very last, and the servant of all.”

36He took a little child whom he placed among them. Taking the child in his arms, he said to them,

37“Whoever welcomes one of these little children in my name welcomes me; and whoever welcomes me does not welcome me but the one who sent me.”

38“Teacher,” said John, “we saw someone driving out demons in your name and we told him to stop, because he was not one of us.”

39“Do not stop him,” Jesus said. “For no one who does a miracle in my name can in the next moment say anything bad about me,

40for whoever is not against us is for us.
