The GB will release 'new light'. "Recently new light has revealed that the governing body alone are the faithful slave, and were we not appreciate for the governing body having shared this new light? The trumpets of truth have shone more new light! Evidently, since the faithful slave is entrusted with all his master belongings, the faithful slave is actually the representation of the master, and as such, the faithful slave is to be worshiped as the master would be, because in worshiping the faithful slave, one is in actuality worshiping the master. From here on, all talks will be televised from the GB directly worldwide. All chairs will be removed from the kingdomhalls and replaced with prayer rugs. Everyone will bow low in worship as they take in the divine teachings from the master himself through the faithful slave, the governing body.
I think it's more likely to go something like this: Since the master will appoint the FDS as the master of all his belongings, how much more so should you do the same? The GB is proud to announce that they are willing to help you oversee all your worldly possessions. They'll provide legal services for you to sign over any property to them, as well as have your paychecks be auto-deposited in their accounts. They will provide you with an allowance that will cover your living expenses.
What a loving provision it is that they are willing to take responsibility for these unrighteous riches and material possessions to allow us to better focus on spiritual things and store up treasures in heaven.
