Commandments are the railroad tracks on which the life empowered by the love of God poured into the heart by the Holy Spirit runs. Love empowers the engine; law guides the direction. They are mutually interdependent. The notion that love can operate apart from law is a figment of the imagination. It is not only bad theology; it is poor psychology. It has to borrow from law to give eyes to love.
