Mark 9:38-41

38John said to Jesus, “Teacher, we saw someone forcing demons out of a person by using the power and authority of your name. We tried to stop him because he was not one of us.”

39Jesus said, “Don’t stop him! No one who works a miracle in my name can turn around and speak evil of me.

40Whoever isn’t against us is for us.

41I can guarantee this truth: Whoever gives you a cup of water to drink because you belong to Christ will certainly not lose his reward.”
