That expression goes back a long way I guess, I think probably used by the Org. itself in a WT Mag ??
That always sounded weird to my English ear, I had a mental picture of me carrying a tray with a Drink on to Jehovah ! With me in a Waiter's Uniform ! But I have heard many English J.W's come out with that one !
I am sure it was started as a Mind Control phrase, for all those who were saying, to quote the Buybull : "But where is this promised presence of his ?".
