Observe too, the unclean spirit's knowledge, not only of the birthplace and name, but of the character and divine relationship of Jesus. That is one of the features of demoniacal possession which distinguish it from disease or insanity, and is quite incapable of explanation on any other ground. It gives a glimpse into a dim region, and suggests that the counsels of Heaven, as effected on earth, are keenly watched and understood by eyes whose gleam is unsoftened by any touch of pity or submission. It is most natural, if there are such spirits, that they should know Jesus while men knew Him not, and that their hatred should keep pace with their knowledge, even while by the knowledge the hatred was seen to be vain. Observe Christ's tone of authority and sternness. He had pity for men, who were capable of redemption, but His words and demeanour to the spirits are always severe. He accepts the most imperfect recognition from men, and often seems as if labouring to evoke it, but He silences the spirits' clear recognition. The confession which is 'unto salvation' comes from a heart that loves, not merely from a head that perceives; and Jesus accepts nothing else. He will not have His name soiled by such lips. Note, still further, Christ's absolute control of the demon. His bare word is sovereign, and secures outward obedience, though from an unsubdued and disobedient will. He cannot make the foul creature love, but He can make him act. Surely Omnipotence speaks, if demons hear and obey. Their king had been conquered, and they knew their Master. The strong man had been bound, and this is the spoiling of his house. The question of the wondering worshippers in the synagogue goes to the root of the matter, when they ask what they must think of the whole message of One whose word gives law to the unclean spirits; for the command to them is a revelation to us, and we learn His Godhead by the power of His simple word, which is but the forth-putting of His will. We cannot but notice the lurid light thrown by the existence of such spirits on the possibility of undying and responsible beings reaching, by continued alienation of heart and will from God, a stage in which they are beyond the capacity of improvement, and outside the sweep of Christ's pity.
