In the Bible, a person calls Jesus "Good Master", but Jesus tells him that no one is good, but God. This was used by a Jehovah Witness to try to deny the deity of Jesus to me, and I wasn't able to answer this question. Of course, I would never fall into their false doctrines, I know a lot about their false teachings. But, I didn't have the answer at the moment. Can someone give me an explanation of this verse?
