The reasons why we have authority is too guide little children who are "innocent" and have no experience or wisdom. To lead them in the right direction by someone who is wise.

In the Biblical Perspective we need guidance because we are weary and are fools with no knowledge. Therefore God said listen to your mother and father for they are wise, and have wisdom in them.

In Lord of the Flies, Piggy has the characteristic of knowledge. Since the beginning he was responsible and had lots of knowledge for his age especially being stranded on an island with 12 year old boys.

In life we go through difficult times. God shapes us into better people so we can strive to be more like him. We sometimes listen to what the world has to say instead of God, because it is in our sin nature. Even though we are in perfect God puts people in our lifes to guide us and make us better people.
