I think people get confused about law and grace because they don't understand that Jesus living within us by His Spirit simply changes everything and way we view life. We DO become a new creature.
The closer and more we learn of Jesus “through His eyes rather than our own”...the more we enjoy and want to please him. Rather like the relationships within a marriage....you do and don't do certain things because of your love for them and the bond you have nurtured along with them.
Wonderful depiction of the process of Sanctification!
