Paragraph 9 in tomorrow's lesson says: "For many years, God's people found this approach to Bible accounts faith strengthening."
Yes, nothing is as faith strengthening as having teachings and prophecies completely change every few years.
That and using the fallacies of appeal to authority and bandwagon. "We're (the GB appointed by Jeezus) telling you it was faith strengthening. And Andre said, 'Evolution of my beliefs is faith strengthening.'"
