Please do not put words in my mouth. I am saying nothing of the sort. I am saying they simply do not do prophecy. They only have understandings from already written Bible prophecies and chronology this is not the same.
If someone writes a complicated map for someone else to use with written instructions that need them to use a compass and recognise certain landmarks as they travel to a specific destination. The person that then uses this map even if they make mistakes on it are not writers of the map they are only users of the map. And we are told to use it. If we don't use it we will never get to our destination.
