That makes perfect sense. The brochures are just like the public version of the Watchtower mag. I do not understand how God's communication channel is still teaching the "old light" . Certainly, the Watchtower Society is not used by God in any way.
How long has the Watchtower Society taught this false "generation" teaching? The link(s) below indicates at least 10 years because complaints were made 10 years ago of this very thing.
Where you will find this link http://www.watchtowernews.org/generationquotes.htm
Yet the Society refuses to take down it's own APOSTATE material.
