We are encouraged - if fact as soon as one begins to study - to "make the Truth your own." This doesn't mean to become a serious student of the bible. It means to become fully immersed in the the religion - the organization, the congregation, the meetings. You must surrender your ability to reason and begin to think and feel as a JW.
Many who have come into the organization with a good education and a professional career will give up their personal power to the religion. We all are trained to become like children - dependent on WT doctrine and policy to govern our lives. Complex issues and questions facing the individual, mankind and even the universe can be answered very simply through a magazine article or a chapter in a book.
We cease to investigate and reason on our own.
