This article is about the interactions between Goliath and Saul.  Both of these men are very easily defined.  Saul is certaintly worthy and capable of being a king, while Goliath relates more with a warrior.  Throughout the article, it is able to communicate a sense of the connection or lack of between apperances and reality.  Then, everyone is thrown off by the misconception of looks when David, who is only a shepard, turns out to be one of the most accomplished kings and warriors in the Israelite society.  A quote written in the artcle: "Look not on his countenance, or on the height of his stature; because I have rejected him; for it is not as man seeth: for man looketh on the outward appearance, but the Lord looketh on the heart" is able to identify the main theme that is being communicated in the story of Goliath and Saul.  David, who ends up winning in the end, owes his success not to God, but to his faith in God. 

The last sentence of the article perfectly defines the whole things and relates it back to life today. "When thinking about world conditions today, and in particular about the real sources of Israel’s strength as a nation, careful readers of the David and Goliath story might do well to bear in mind its central message: things are not always as they are seen, or as others wish us to see them." This quote is saying that sight is a bias sense to rely on.  If you rely too much on it, you could morph the reality into what you wish was there.  This is important to realize and be aware of in life.  Everyday, people are judged based upon their looks, gender, and the color of their skin.  Based on this, people's oppurtinity's are either dimished or increased depending of the other person's judgement of them.  This is a problem because the person may not always be suitable for the position or whatever
