So God and Jesus are both out of the picture. So where in the bible does it say to obey the "faithful and discreet slave"? The phrase only occurs once and they were to obey the master (some think that is Jesus) not have someone obey them.
*** w11 7/15 p. 28 par. 17 God’s Rest—What Is It? ***On the other hand, if we minimized the Bible-based counsel that we receive through the faithful and discreet slave class, choosing to follow an independent course, we would be placing ourselves at odds with God’s unfolding purpose. This could endanger our peaceful relationship with Jehovah. (not our relationship with Jesus?)
*** w11 7/15 p. 28 par. 16 God’s Rest—What Is It? ***We can enter into Jehovah’s rest—or join him in his rest—by obediently working in harmony with his advancing purpose as it is revealed to us through his organization. (not through God or the bible?)
*** w09 10/15 p. 15 par. 14 “You Are My Friends” ***Many of those first-century Christians had known Jesus personally or had seen him after his resurrection. Obviously, we have not had that privilege. How, then, can we be friends of Christ? One way is to obey the direction provided by the faithful and discreet slave class, which consists of Jesus’ spirit-anointed brothers still alive on earth. Jesus promised that during “the conclusion of the system of things,” he would appoint this slave “over all his belongings.” (Matt. 24:3, 45-47)
*** w07 12/15 p. 19 par. 15 “Stand Firm and See the Salvation of Jehovah” ***What else can we learn from Israel’s Exodus from Egypt? That we must obey Jehovah no matter what he asks us to do. The Israelites were obedient in carrying out the detailed preparations for the Passover. They obediently stayed indoors during the night of Nisan 14. When they finally left Egypt, they had to go “in battle formation.” (Exodus 13:18) Today, it is so important that we follow the guidance that comes to us through “the faithful and discreet slave”! (Matthew 24:45)

By Following Theocratic Direction: “Theocracy” means “rule by God,” who is love. We benefit from his rule by accepting his authority and following his instructions in large and small decisions. “The faithful and discreet slave” represents theocratic rule on this earth. (Matt. 24:45-47) Cooperation with the organization that the “slave” uses is vital if we are to obtain Jehovah’s blessing. (Compare Hebrews 13:17.)
