Mark 9:36-41

And he took a little child, and set him in the midst of them: and taking him in his arms, he said unto them, Whosoever shall receive one of such little children in my name, receiveth me: and whosoever receiveth me, receiveth not me, but him that sent me. John said unto him, Teacher, we saw one casting out demons in thy name; and we forbade him, because he followed not us. But Jesus said, Forbid him not: for there is no man who shall do a mighty work in my name, and be able quickly to speak evil of me. For he that is not against us is for us. For whosoever shall give you a cup of water to drink, because ye are Christ’s, verily I say unto you, he shall in no wise lose his reward.
