These exorcists had no faith. All that they knew of Jesus was that He was the one whom Paul preached.' Even the name of Jesus is spoiled and is powerless on the lips of one who repeats it, parrot-like, because he has seen its power when it came flame-like from the fiery lips of some man of earnest convictions.
In all regions, and especially in the matter of art or literature, imitators are poor creatures, and men are quick to detect the difference between the original and the copy. The copyists generally imitate the weak points, and seldom get nearer than the imitation of external and trivial peculiarities. It is more feasible to reproduce the contortions of the Sibyl' than to catch her inspiration.'
This absence or feebleness of personal faith is the explanation of much failure in so-called Christian work. No doubt there may be other causes for the want of success, but after all allowance is made for these, it still remains true that the chief reason why the Gospel message is often proclaimed without casting out demons is that it is proclaimed with faltering faith, tentatively and without assured confidence in its power, or imitatively, with but little, if any, inward experience of the magic of its spell. The demons have ears quick to discriminate between Paul's fiery accents and the cold repetition of them. Incomparably the most powerful agency which any man can employ in producing conviction in others is the utterance of his own intense conviction. If you wish me to weep, your own tears must flow,' said the Roman poet. Other factors may powerfully aid the exorcising power of the word spoken by faith, and no wise man will disparage these, but they are powerless without faith and it is powerful without them.
Consider the effect of that personal faith on the speaker--in bringing all his force to bear on his words; in endowing him for a time with many of the subsidiary qualities which make our words winged and weighty; in lifting to a height of self-oblivion, which itself is magnetic.
Consider its effect on the hearers--how it bows hearts as trees are bent before a rushing wind.
Consider its effect in bringing into action God's own power. Of the man, all aflame with Christian convictions and speaking them with the confidence and urgency which become them and him, it may truly be said, It is not ye that speak, but the Spirit of your Father that speaketh in you.'
Here then we have laid bare the secret of success and a cause of failure, in Christian enterprise. Here we see, as in a concrete example, the truth exemplified, which all who long for the emancipation of demon-ridden humanity would be wise to lay to heart, and thereby to be saved from much eager travelling on a road that leads nowhither, and much futile expenditure of effort and sympathy, and many disappointments. It is as true to-day as it was long ago in Ephesus, that the evil spirits feel the Infant's hand from far Judea's land,' and are forced to confess, Jesus we know and Paul we know'; but to other would-be exorcists their answer is, Who are ye? When a strong man armed keepeth his house, his goods are in peace.' There is but One stronger than he-who can come upon him, and having overcome him, can take from him all his armour wherein he trusted and divide the spoils,' and that is the Christ, at whose name, faithfully spoken, the devils fear and fly.'
