As it says in Ephesians, evangelists are only one gift that Christ gave the congregation. In the witness idealogy you must be an evangelist or cannot be fully excepted into the congregation. For example if you are considered inactive you cannot become a MS thus not a good marriage prospect. So the real question is not; Is preaching a waste of time? It should be; Are the Governing Body acting as Pharisees imposing rules about preaching that are not found in the bible?
