Allegory of the Olive Tree

I teach gospel doctrine every Sunday.  Today's lesson was on Zenos' Allegory of the Olive Tree.  I came across the article (an excerpt from The Allegory of the Olive Tree).  The article adds some interesting insight to the allegory.  Here's the link.  http://maxwellinstitute.byu.edu/publications/books/?bookid=124&chapid=1466
