38John asserted to him, "Teacher, we saw someone casting out demons in your name, and we prevented him, because he was not following us."39But Jesus said, "Do not prevent him, for no one who will do a mighty work in my name will be able quickly to speak evil of me."40For whoever is not according to us is for us.41Whoever gives you a cup of water to drink in the name because you are of Christ, truly I say to you that he will certainly not lose his wage.
