As many ex Jws here will back me up on this one, and take it from people who have been there done that got the tshirt for many many many many many years of their lives, Crisis of Conscience is a book to read! By raymond franz, a former governing body member of the WT$.
To begin with, you will be love bombed by these people into making you beileve it really is so called 'truth'
Dont waste your life, you will be indoctrinated, brainwashed and a bible study (which they call it) is NOT a bible study at all.
They use a book called what does the bible really teach. And any answer you give to a question if it is not in line with their teachings, they will tell you it is the wrong answer and correct you to what they beileve.
When you answer questions from this book with them and you answer them in line with their teachings from the book, they will tell you it is correct.
It is an indoctrination process, NOT a bible study.
Also, their bible which they cliam is the most accurate translation of the holy scriptures, is in fact FAR from it.
They have tampered with the bible to suit their own teachings.
Do not be misled!
Read 2ndJohn 1:7.
