The prophets have been for me the proverbial bar of soap in the shower.  While I have loved them, the prophecies and their organization have eluded my grasp.   Until recently.  I reread a series of books that I read many years ago.  And once again, my understanding and comprehension of the prophets was like getting my annual contact prescription updated–I can see much better.  So with that I highly recommend the following books by Lynn Austin:  Gods and Kings Series and Redemption Chronicles Series.  Very worth it.
