Jehovah's Witnesses believe all their doctrines, beliefs, and rules come from God. i.e. the rules come directly from God through the 'faithful and discreet slave', rather than from their Governing Body. The organization is thought to be merely an instrument or tool used God so that people can learn 'the truth' and be saved at armageddon
Jehovah's Witnesses believe they trust and obey God's slave as instructed by Jesus in Matthew 24: 45-51. However there's absolutely no Bible based evidence that Jesus appointed anyone to take his place and dispense spiritual food.
Since the meaning of Matthew 24:45-51 is unknown, the reality is that Jehovah's Witnesses trust and obey the Governing Body of Jehovah's Witnesses, - not God.
The Watchtower says, 'Today, the Governing Body represents the faithful and discreet slave class. There was a similar arrangement in the first century'. Watchtower June 15, 2009. Article: 'The Faithful Steward and Its Governing Body'.
In the article about mind control, critics say that the unique language of Jehovah's Witnesses keeps them in a hypnotic dream-like state, fearing something that does not exist. They fear a small group of men, i.e. the top leaders within their organization in the same way they fear God. They are compelled to obey and completely trust the teachings of these few individuals as if everything they say come from God. Jehovah's Witnesses believe these mortal men are God's channel of communication.
