George Lucas was raised a Methodist and it seems that Star Wars is nothing but, as a wise man once said, a passion play. Indeed, we find something of John Wesley in Star Wars:

Wesley taught that humankind was not completely depraved… And remember what Luke Whineywalker said about Darth? “There is some good still in him.” Indeed, Darth had to choose to be brought back to the Force, and found himself on the journey back towards perfection. It was his choice, and he made it.
