Mark 9:38-41; Acts 16:18

Mark 9:38-41

38 John said to him, "Teacher, we saw a man casting out demons in your name, and we forbade him, because he was not following us."

39 But Jesus said, "Do not forbid him; for no one who does a mighty work in my name will be able soon after to speak evil of me.

40 For he that is not against us is for us.

41 For truly, I say to you, whoever gives you a cup of water to drink because you bear the name of Christ, will by no means lose his reward.

Acts 16:18

18 And this she did for many days. But Paul was annoyed, and turned and said to the spirit, "I charge you in the name of Jesus Christ to come out of her." And it came out that very hour.
