Tiawani, you have recieved good advise here. If you want to know about their doctrines - read their literature, if you want to know about their lifestyle - ask us. Active JW's will give you a glimpse of their lives (through rose colored glasses) if you ask them.
Here are a few of their beliefs - there are thousnads more, but this is a start:
1- There is no "trinity", there is Jehovah God, Jesus His son, and the Holy Spirit through which/whom Jehovah acts. Each of these are a separate entity.
2- There is no hell, when you die you simply dont exist anymore.
3- There is a heaven, but only 144,000 humans will ever be admitted - most of whom are already there, approx. 8,600 remain.
4- Armaggedon will occur before those 8,600 pass away.
5- Satan and his demons inhabit the Earth (there is no hell), and they actively oppose Jehovah's organization through persecution and possesion of people and objects.
6- Anyone not in Jehovah's organization when armaggedon occurs will be destroyed.
7- Jesus Christ's return was prophesied in the Bible, JW's believe He has already returned (invisibly), and is currently ruling in Heaven.
8- All teaching and biblical interpretation comes from the Watchtower Bible and Tract Society, and the Governing Body who write their materials. They are taught that these teachings, all books, magazines, tracts, and even their translation of the bible are sent directly from God to the the Governing Body, and are therefore NOT to be questioned.
Others on this board may be able to add some more, I hope this helps.
