Harry Potter and Divine Foreknowledge

The end of the chapter of Harry Potter and the Half-Blood Prince entitled "Horcruxes" is probably one of the most intellectually challenging passages in the entire Harry Potter series. It deals with the relationship between the prophecy regarding Harry and Lord Voldemort, and the fulfillment of that prophecy. I think it can be of use in explaining how free will and divine foreknowledge can coexist, though the discussion in Harry Potter is not entirely analogous.
