People are imperfect vessels for revelation, but it is all we have.  Like I said God does not give dictation.  What part of NOT don't you get.  Example, Paul relied on his Rabbinic past when writing his letters and his deeply held belief in the imminent return.  The second did not happen.  John of Patmos was deeply affected by the loss of Jerusalem and the belief that Pauline Christianity was the Harlot.  He also believed in imminent return.  No again.  Imperfect vessels.
