Obedience

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

Boyd K. Packer

To be obedient means you won't be incarcerated. Follow the law and you won't go to prison or jail. You follow the law and you are able to go wherever you want no will stop you. 

Being obedient won't land you in prison it  make sure you are free. It is like a car and you filling the car is what you're supposed to do or else you wont go anywhere without the tank having gas.
