John Calvin on Luke 13:12

12. Woman, thou art delivered In this miracle, as well as in others, Christ exhibited a proof both of his power and of his grace; for in this manner he testified that he had come for the purpose of granting relief to the wretched. His power is expressed in these words, Woman, thou art delivered; for he authoritatively declares that deliverance was at his own disposal, and employs, at the same time, the outward sign, the use of which we have explained on a former occasion.
