Thank you for correcting my typo, obviously I meant "has" rather than "was."
I have been studying the book of Isaiah for a couple of years and it is apparent to me that there are many things that Jehovah has not yet revealed to his organization as a whole. That thought is born out in the verse at Isaiah 48:6-7, which reads: "I have made you hear new things from the present time, even things kept in RESERVE, that you have not known. At the present time they must be created, and not from that time, even things that before today you have not heard, that you may not say, 'Look! I have already known them."'
These things that God has in reserve are prophecies that his people have not been allowed to discern fully. In some cases we have misapplied certain things, as did the apostles, so in that way God conceals his secrets from his servants until such time as he is ready to reveal them. What this means then, as far as the apostasy is concerned, is that Jehovah has dismissed those from his organization with disinformation yet they imagine that they are fully informed and know all that is to be known about the Bible. It is the same principle that caused Jesus to publicly praise Jehovah for concealing his truth from the intellectuals of his day and revealing them to babes. In my estimation the book of Isaiah is the primary key to deciphering all the other prophecies. / You Know
