You received a spirit of adoption as sons, by which spirit we cry out: “Abba, Father!”—Rom. 8:15.
Those who have received this special invitation from God do not need another witness from any other source. They do not need someone else to verify what has happened to them. Jehovah leaves no doubt whatsoever in their minds and hearts. The apostle John tells such anointed Christians: “You have an anointing from the holy one, and all of you have knowledge.” He further states: “As for you, the anointing that you received from him remains in you, and you do not need anyone to be teaching you; but the anointing from him is teaching you about all things and is true and is no lie. Just as it has taught you, remain in union with him.” (1 John 2:20, 27) These ones need spiritual instruction just like everyone else. But they do not need anyone to validate their anointing. The most powerful force in the universe has given them this conviction! w16.01 3:9, 10
If you actually accept what the verse plainly says then it logically follows that all anointed ones don't need to be taught by a select group called the GB. But that of course is not acceptable, so they completely deny that and make up their own interpretation that in no way can possibly be construed from the actual text! IT says their anointed will teach them ALL things, not just the validity of their anointing....
