The narrative suggests some affinity between the demoniac and the animal nature, and though it is easy to ridicule, it is impossible to disprove, the suggestion. We know too little about either to do that, and what we cannot disprove it is somewhat venturesome hardily to deny. There are depths in the one nature, which we cannot fathom though its possessors are close to us; the other is removed from our investigation altogether. Where we are so utterly ignorant we had better neither affirm nor deny. But we may take a homiletical use out of that apparent affinity, and recognise that a spirit in rebellion against God necessarily gravitates downwards, and becomes more or less bestialised.
No wonder that the swineherds fled, but, surely, it is a wonder that eagerness to be rid of Jesus was the sole result of the miracle. Perhaps the reason was the loss of the swine, which would bulk largest in their keepers' excited story; perhaps the reason was a fear that He would find out and rebuke other instances of breach of strict Jewish propriety, perhaps it was simply the shrinking from any close contact with the heavenly, or apparently supernatural, which is so instinctive in us, and witnesses to a dormant consciousness of discord with Heaven. 'Depart from me, for I am a sinful man,' is the cry of the roused conscience. And, alas! it has power to send away Him whom we need, and who comes to us, just because we are sinful, and just that He may deliver us from our sin.
