Mark 9:38-41

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.

41And whoever gives you a cup of water to drink in my name, because you belong to Christ — truly I tell you, he will never lose his reward.
