Everything that can appeal to the modern man, the last word in presentation is used, in the belief that when it is done, and you do it with a modern technique, then you will get hold of the modern man. But I think that the time has now come to ask this simple question: what are the results? Is the modern problem being touched at all? Of course these various methods, the apologetics and the others may indeed lead to individual conversions. We are all aware of that. Almost any method you like to employ will do that. Of course there are individual conversions, but my question is this—what of the situation, what of the bulk of men and women, what of the working classes of this country, are they being touched at all, are they being affected at all? Is anybody being affected, except those who are already in the Church or on the fringe of the Church? What of the spiritual and religious condition of the country? What of the whole state of society? Is this being touched at all by all our activities?
Well, my answer would be that it all seems to put us into the position of the disciples who had tried to cast the devil out of the boy, these men who had been so successful in many another case, but who could not touch this case at all. And our Lord gives them the explanation, ‘this kind’ can come forth by nothing like this. By what, then? ‘This kind can come forth by nothing but by prayer, and fasting.’ You failed there, he said in effect to these disciples, because you did not have sufficient power. You were using the power that you have, and you were very confident in it. You did it with great assurance, you were masters of the occasion, you thought you were going to succeed at once, but you did not. It is time you paused for a moment and began to think. It was your ignorance of these gradations in power amongst evil spirits that led to your failure, and to your crestfallen condition at this moment. You have not sufficient power. I did what you could not do because I have power, because I am filled with the power that God gives me by the Holy Spirit, for he gives not the Spirit by measure unto me. You will never be able to deal with ‘this kind’ unless you have applied to God for the power which he alone can give you. You must become aware of your need, of your impotence, of your helplessness. You must realise that you are confronted by something that is too deep for your methods to get rid of, or to deal with, and you need something that can go down beneath that evil power, and shatter it, and there is only one thing that can do that, and that is the power of God.
