What they really mean is 'blind faith'. Those with blind faith will:
1) Neglect their education, settle for dead end jobs and not prepare for the future because the GB says devote that time and money to the org. "The New System is coming soon so why bother?"
2) Will slave until they drop 'doing more' (which will never be enough) and never do anything they really want to. "You can do all that in the New System!"
3) Will make martyrs of themselves or worse, their innocent kids, by refusing blood transfusions. "Don't mourn. You'll see them again in the New System! Maybe. If you toe the line."
4) And will follow the slightest whims of the GB without allowing themselves to ask questions. "They're our ticket to the New System!"
