Obedience

"The key to freedom is obedience.  The more obedient we are, the more freedom we have."

This quote is telling us that we have are obedient then we will get more previledge will have. For example if you want to go out with your friends and  you have been misbehaving you will not be able to go out and have fun. If you do behave well then your parents will let you go out and possibly for longer time as well.
