Witnesses use a special translation of the Bible - The New World Translation, which sometimes translates key passages, such as those about the nature of Jesus Christ, differently than other reputable English-language Bible translations.(Compare John 1:1-3 and Philippians 2:5-8 in the New World Translation and the King James Version or the New International Version.) Jehovah's Witnesses believe in one God, the Creator of the universe and the God of the Hebrew and Christian scriptures.The feeling is mutual, however: Jehovah's Witnesses deny that other Christian groups are true Christians. The nations and churches of Christendom were not, and are not, Christian. His inspired Word says of them: "They publicly declare they know God, but they disown him by their works, because they are detestable and disobedient and not approved for good work of any sort."Christendom" is defined as that part of the world where Christianity prevails. Rather, Witnesses expect and encourage their members to strive to do God's will and remain pure in his eyes. For Jehovah's Witnesses, the purpose of life is to earn the right to participate in God's future Kingdom on earth, and to help others to do so.But eternal life comes not simply from faith in Jesus but from "learning about Jehovah and obeying his requirements," proving oneself to be God's loyal subject, and listening to the Kingdom message and acting on it. Instead, they hold that the souls of the wicked will be annihilated.The death that Adam brought into the world is spiritual as well as physical, and only those who gain entrance into the Kingdom of God will exist eternally.

A belief that is unique to Jehovah's Witnesses is that the eschatological events predicted in Revelation began in 1914.This is when God gave Jesus his Kingdom, and Jesus has been ruling from heaven ever since.At this time Jesus threw Satan and his demons out of heaven and down to earth, which is why, according to Witnesses, the world has been getting progressively worse since 1914.
