Age is a quantitative scale not a qualitative measure of a person. At 20 we are told "you are too young to do these things" then at 30 we are told "you're too old to do these things". So, according to the rules of men, we are only allowed to "live" for 8 or 9 years? That is not what life is meant to be. That is not what God has said- that is what man has tried to teach us.
The rules of mean are made to control people not liberate us. The rules of society are mostly built on prejudice and fear rather than on wisdom and love. Clearly, I am not speaking about incarcerating a thief or murderer or rapist, I am talking about the everyday rules that people have made to tell us do not touch, stay within a certain age range of people you see and activities in which you participate.
Rules are made for manipulation like pop fashion and pop- well- anything. Rules of what to wear, what to see, what to do and with whom to see them are meant to take your money and liberty at the same time.
Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations—"Do not touch, do not taste, do not handle," which all concern things which perish with the using—according to the commandments and doctrines of men? These things indeed have an appearance of wisdom in self-imposed religion, false humility, and neglect of the body, but are of no value against the indulgence of the flesh. (Col 2:20-23)
