How does operating in love relate to fulfilling the whole Law?
Operating in agape love, which results from the Holy Spirit's indwelling and outworking, makes a person a fulfiller of the whole Law. Because this love seeks the other person's highest good and enhances what is good, it affects lifestyle and thereby fulfills the Law.
Les explains that this is agape love, which comes as a result of the indwelling and outworking of the Holy Spirit, and it will have an effect on our lifestyle. When love seeks the other person's highest good, it does nothing but enhance the things that are good. Therefore, we become fulfillers of the whole Law just by virtue of our operating love. This inward love contrasts with outward circumstances, just as joy comes from within while happiness depends on circumstances.
