Jehovah's Witnesses believe they are organized to do Jehovah's will and they are the only ones who are 'in the truth'. Everyone else has 'false' beliefs and they are 'out of the truth' This is the unique language Jehovah's Witnesses use. 
The Watchtower says that "Rebellion against the slave is rebellion against God." Watchtower June 1, 1956 page 346 par 11. The Watchtower June 15, 2009 pages 23, 24 says. 'Today, the Governing Body represents the faithful and discreet slave class.'.  See Matthew 24:45-51
However in their literature they say that their organization has no divine inspiration and can make mistakes. Which message is correct? Are they the only ones with truthful beliefs? Or is it possible that they are wrong about some things because they have no divine inspiration?
If it's true that God is not in communication with the Watchtower Society, is it possible that they are wrong about God's will and what He requires?
It would seem logical that if the Watchtower has no divine inspiration, then truth and falsehood must exist in all religions including the Jehovah's Witness faith. However the Watchtower strongly believes Jehovah's Witnesses are the chosen ones God will save when this wicked system of things dominated by Satan the Devil comes to an end.
Is it true that they are God's messenger and the only channel through which God speaks? Is it true that God loves only Jehovah's Witnesses and all other people are controlled by Satan the Devil?
The Watchtower says that according to the Bible "Only Jehovah's Witnesses, those of the anointed remnant and the "great crowd," as a united organization under the protection of the Supreme Organizer, have any Scriptural hope of surviving the impending end of this doomed system dominated by Satan the Devil." Watchtower Sept 1, 1989 page 19.
The Bible says Jesus has 'the words of eternal life' John 6:67-69. True Christians are faithful to the teachings of Jesus alone because he has the words of eternal life. Jesus is their only path to God because he is the mediator between God and man. 1 Timothy 2:5 NIV The Watchtower interprets the Bible differently.

Check out these links and see why some believe the Watchtower opposes God's will:
1. Jehovah's Witnesses are proud of their unique language only they understand. Their words spoken over and over again keeps them firmly attached to Watchtower beliefs even if they decide to leave. Jehovah's Witnesses who leave often feel guilty and depressed. Why? Because as long as they unconsciously continue to use the same words after they leave, they remain firmly under the control of the Watchtower. They can't seem to move on. Learn how mind control works.

3. What was 'the truth' between 1966 and 1975 according to the Watchtower? Were Jehovah's Witnesses organized to do Jehovah's will prior to 1975? They thought they were. Some faithful Witnesses quit their jobs and sold their homes to go door to door full time, warning the wicked. Many of them had just enough money to last until 1976. What happened? Why didn't armageddon come in 1975? Find out what happened before 1975
