Traditionally – and particularly in older films – you could easily tell the difference between good guys and bad guys: good guys wore white; bad guys wore black. Think of Luke Skywalker and Darth Vader in the first Star Wars movie.

Or think of some of the older mystery movies – it’s a foggy night in London, a perfect setting for a murder to take place. Bad things happen at night, under the cover of darkness. Good things happen in daytime under the bright light of the sun.

Well, we know that life isn’t the simple, and good and bad aren’t so easily differentiated, but it’s a powerful contrast and our lesson today builds on it.
