The use of rules to keep us from worldliness is carnal, for like the law it is consciousness of sin. Restraints entice rebellion, a perpetual temptation. Any "ought" is  in service to soul, not spirit. Freedom is in "want to" and not "ought to. Hidden in Christ, what is commanded is the desire of our new spirit. It comes from within, by grace, not from without, by effort to obey standards. "Turning the other cheek" comes from the muscle of joy, a delight in mercy. 

The principles given to us by Christ are meant to be revelatory, not regulatory, their purpose to expose and help us realize both the emptiness of worldly treasures and the faults within us that make for attachments to them. It is light to reveal the dark reaches within us and offer these up for healing. "Dying to self."  This is a continual practice, putting these principles before personalities (both our own and that of others). To me, this is part of picking up our cross. Yet all that we truly sacrifice is that which is keeping us from our greatest freedom and deepest joy.

Nonattachment to image, to prosperity, to success, to failure, to certainty, to comfort, to safety, to control, to knowing, to reward, to punishment, to acceptance, to belonging, to all that is not Eternal. To live on earth as if if already in heaven is the freedom we find in Christ.
