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.
Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
