One of my favorite books is Dune. A story about a desert planet rich in 'spice' (which is oil) and the whole galaxy revolves around it, until a Messiah comes and resets the political schema (a kingdom). In the book, there is a reference to "the sleeper", who is the Messianic figure. Consider Ephesians 5:14 "Wake up, sleeper, rise from the dead, and Christ will shine on you." I'm guessing the author Frank Herbert took the idea of the sleeper from the Bible (he also wrote Islamic ideas into the book). Who is this sleeper? Why are half of the bridegroom asleep? When they wake up, what will change?
