The main lesson of the Star Wars series (one possible reading) is how badly people screw things up when they think they understand "the will of the Force", or, by analogy, some other all-powerful supernatural entity. For example- Qui-Gon (for those who've never seen the prequel movies, well, I'm not going into a complete explanation here- sorry) thought he knew the will of the Force was for him to train Anakin. Result- the end of the Jedi, the rise of Vader, the fall of the Republic, and (so far! I haven't seen the last movie yet) at least 3 generations of turmoil and misery.

People who think they know the "will" of any mystical entity outside of themselves are just deluding themselves and no good will come of them. Yes, religious adherents, I'm talking about you.
