My question is who has given the GB of the WTBTS the O.K. to build these larger facilities in the first place? Certainly not Jesus Christ or Sky Daddy, for that matter!
Jesus, as stated in Mat 24:45-47, hasn't yet assigned 'all his earthly belongings' to anyone. That is something he will do in the future during the Great Tribulation according to the latest updates found in the July 15, 2013 Study Edition of the Watchtower.
And as mentioned in the April 1, 2007 Watchtower pg 23 par 7-9 notice what 'all those earthly belongings' include:
'“all his belongings.” What would this entail? ...... the supervision of the material facilities used by Christ’s followers to carry out their Christian activities, such as the world headquarters and branch offices of Jehovah’s Witnesses, as well as their places of worship—Kingdom Halls and Assembly Halls...'
So as usual WT is way ahead of itself on this Bethel compound.
Jesus has yet to give anyone permission to build or has yet to assign any other kingdom earthly assets (belongings) to anyone!
