“We learn from this, that God does not rest satisfied with the outward appearance of works, but chiefly demands the inward feelings, that from a good root good fruits may grow” (John Calvin). Love is not primarily a feeling, but Jesus certainly wants feeling and action to agree. We must act in a loving way even if the feeling is not present, but to feel love while acting is even better. Pray that your actions would always be a result of the love you possess.
