Today's Watchtower lesson instructs Witnesses not to think for themselves when it comes to Bible understanding:
Augest 1, 2001, p. 14, par. 8:
First, since "oneness" is to be observed, a mature Christian must be in unity and full harmony with fellow believers as far as faith and knowledge are concerned. He does not advocate or insist on personal opinions or harbor private ideas when it comes to Bible understanding. Rater, he has complete confidence in the truth as it is revealed by Jehovah God through his Son, Jesus Christ, and "the faithful and discreet slave." By regularly taking in the spiritual food provided "at the proper time" -- through Christian publications, meetings, assemblies, and conventions -- we can be sure that we maintain "oneness" with fellow Christians in faith and knowledge. -- Matthew 24:45.
