Wherever Christ went, he confirmed his Divine mission by miracles, which were emblems of the healing power of his doctrine, and the influences of the Spirit which accompanied it. We do not now find the Saviour's miraculous healing power in our bodies; but if we are cured by medicine, the praise is equally his.
Three general words are here used. He healed every sickness or disease; none was too bad; none too hard, for Christ to heal with a word. Three diseases are named; the palsy, which is the greatest weakness of the body; lunacy, which is the greatest malady of the mind; and possession of the devil, which is the greatest misery and calamity of both; yet Christ healed all, and by thus curing bodily diseases, showed that his great errand into the world was to cure spiritual maladies.
Sin is the sickness, disease, and torment of the soul: Christ came to take away sin, and so to heal the soul.
