Mad Irishman if you look on JW.ORG under the heading 'How does the Governing Body function today?' It says the following:-
'It is responsive to the direction of God’s spirit. The Governing Body looks to the Universal Sovereign, Jehovah, and to the Head of the congregation, Jesus, for guidance.'
I actually found this by putting the phrase spirit directed into the search box on that site. Why? Because that's what the JWs have always said. That the Watchtower is not inspired but it is spirit directed. Meaning what? Directed by a supernatural force as Snare said.
