Hello - and welcome to the board Lana .
Becoming a JW is a life-changing commitment to be sure. Take the advise offered here and do your research 'apart' from the Witnesses before you make any drastic decisions, like baptism. They demand way too much from converts for you to take the decision to 'study' with them lightly.
An organization that claims to be THE TRUTH must be able to substantiate those claims apart from it's own recent & current literature. JW beleifs have changed a lot over the years. Do your homework.
Hope you stay around. There are a lot of good researchers on this forum who can direct to various sources, some non-watchtower related, others directly from their own publications.
