Apairo, welcome to the site. Some members here will only criticise & ridicule you for having any kind of faith, while others will try to be constructive and sincerely demonstrate scripturally & factually how the WTBTS is not what it presents itself as - God's chosen organization.
Do serious research into Biblical topics here before your baptism, because after you've done it you will soon discover that you have dedicated yourself to serving the WTBTS - not Jehovah.
If you think I'm lying, ask an elder one or two questions after your next meeting and see what reaction you get. After you get baptised, you'll be punished for asking such questions.
Try these two:
1) Why does "the faithful slave" say that foreigners were only beneficiaries of the Law Covenant and not participants, when Deuteronomy 29:10-15 states clearly that they were?
2) Why does "the faithful slave" say that the Catholic confessional is wrong, but J.W.'s are compelled to confess their sins to elders? Jesus never said anyone was to admit their sins to elders after being confronted by a witness. (Matthew 18:15-17)
Don't walk into such a situation with your eyes and mind closed.
