And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us: and we forbad him, because he followeth not us.
But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me.
For he that is not against us is on our part.
For whosoever shall give you a cup of water to drink in my name, because ye belong to Christ, verily I say unto you, he shall not lose his reward.
Mark 9:38-41 KJV
