Some beliefs
Although Jehovah's Witnesses beliefs come from the Protestant and Adventist tradition, they do hold many beliefs that set themselves apart. The following are some key beliefs that make them different:
Jehovah God: Their God is the God of the Old Testament - all-powerful, all-knowing, and everlasting. They refer to Him as Jehovah - a true, personal, and exclusive name that all should use. The Father, Son, and Holy Spirit: Jehovah's Witnesses do not believe in the Trinity. As mentioned above, God is the all-knowing, all-powerful Creator. The relationship between him and Jesus is like that of father and son: Jesus is the first creation of God. He is fully human. The Holy Spirit is an active force which intervenes for God on earth. All the above mentioned are separate entities.
Satan, the Devil: Satan is seen as an enemy of God. He is misleading and afflicts pain and sorrow. Through spiritism, nationalism, and temptation, Satan leads people astray. The way to resist the devil is by learning about Jehovah.
Man: Jehovah's Witnesses accept the Genesis account of the fall of man. Man is blemished with sin because of the disobedience Adam and Eve showed towards God. Every man is born with sin (save for Jesus, who was born to a virgin). They also believe that man's soul is mortal - i.e. that when a person dies, his spirit (or soul) dies as well. In addition, some will experience eternal life when they are resurrected, in the flesh and soul, simultaneously.
Salvation: In contrast to some Christian traditions that believe salvation is achieved by accepting Christ as Lord ("once saved, always saved"), Jehovah's Witnesses believe it is possible to fall from grace. "The Bible sets forth conditions that must be met if we are to be saved from the effects of inherited sin" (Watchtower, 09/15/89). Accepting Jesus as Lord is essential, but failure to exercise fidelity to God's requirements can result in the loss of the gift of salvation. "elievers...will be saved to eternal life only if they continue to adhere to all of God's requirements...Those losing faith in Jesus also lose everlasting life." (Watchtower, 09/15/89. Thanks to James Long, Webmaster of Jehovah's Witnesses United for assistance in correcting an earlier statement regarding salvation).
Heaven: Heaven is where Jesus Christ and the other "True Christians" will live. There they will rule over the kingdom which will be on earth. Seats are limited: only 144,000 will gain access to heaven.
Hell: Hell is non-existent for the Jehovah's Witnesses. There is not a fiery-torment, claims Russell, because it runs contradictory to God's loving nature. Those who don't qualify for heaven or the kingdom that will be established on earth will simply dissappear, as if they had never existed.
The Great Crowd: These are the subjects of the kingdom ruled by Jesus and the 144,000. They will live forever on the new earth if they have chosen to obey God.
Kingdom of God: This unique government rules over the earth from heaven. Jehovah fulfilled His promise to Jesus that he would rule in 1914. When Jesus became king, Satan and his evil angels were kicked out of heaven and sent to inhabit the earth. This is how the Jehovah's Witnesses explain the wars, crime increases, and other "bad" things which are happening in our world today. All these things indicate that Jesus has established his reign and that we are in the last days. Within a certain time frame, some faithful followers, 144,000 to be exact, will join Jesus and assist him in his reign. After Jesus judges his people (some receiving everlasting life others non-existence), Jehovah will rule again.
Holidays: Jehovah's Witnesses do not celebrate Thanksgiving, Christmas, Easter, birthdays, or any other holidays (save one). They believe these celebrations grew out of ancient false religions. Also, because early Christians did not celebrate these occasions, they believe they should not either. The one day they do celebrate, however, is the Memorial of Christ's Death during Passover.
