It would appear that the disciples were ignorant of the unbelief that had made them weak. They fancied that they had confidence in their Christ-given power, and they certainly had in some dull kind of fashion expected to succeed in their attempt. But He who sees the heart knew that there was no real living confidence in their souls; and His words are a solemn warning to us all, of how possible it is for us to have our faith all honeycombed by gnawing doubt while we suspect it not, like some piece of wood apparently sound, the whole substance of which has been eaten away by hidden worms. We may be going on with Christian work, and may even be looking for spiritual results. We may fancy ourselves faithful stewards of the gospel, and all the while there may be an utter absence of the one thing which makes our words more than so much wind whistling through an archway. The shorn Samson went out to shake himself as at other times,' and knew not that the Spirit of the Lord had departed from him. Who among us is not exposed to the assaults of that pestilence that walketh in darkness? and, alas! who among us can say that he has repelled the contagion? Subtly it creeps over us all, the stealthy intangible vapour, unfelt till it has quenched the lamp which alone lights the darkness of the mine, and clogged to suffocation the labouring lungs.
I will not now speak of the general sources of danger to our faith, which are always in operation with a retarding force as constant as friction, as certain as the gravitation which pulls the pendulum to rest at its lowest point. But I may very briefly particularise two of the enemies of that faith, which have a special bearing on our missionary work, and may be illustrated from the narrative before us.
First, all our activity in spreading the Gospel, whether by personal effort or by our gifts, like every form of outward action, tends to become mechanical, and to lose its connection with the motive which originated it. Of course it is also true, on the other side, that all outward action also tends to strengthen the motive from which it flows. But our Christian work will not do so, unless it be carefully watched, and pains be taken to keep it from slipping off its original foundation, and so altering its whole character. We may very easily become so occupied with the mere external occupation as to be quite unconscious that it has ceased to be faithful work, and has become routine, dull mechanism, or the result of confidence, not in Christ, whose power once flowed through us, but in ourselves the doers. So these disciples may have thought, We can cast out this devil, for we have done the like already,' and have forgotten that it was not they, but Christ in them, who had done it.
How widely this foe to our faith operates amid the multiplied activities of this busy age, one trembles to think. We see all around us a Church toiling with unexampled expenditure of wealth, and effort, and time. It is difficult to repress the suspicion that the work is out of proportion to the life. Ah, brethren, how much of all this energy of effort, so admirable in many respects, will He whose fan is in His hand accept as true service--how much of it will be wheat for the garner, how much chaff for the fire? It is not for us to divide between the two, but it is for us to remember that it is not impossible to make of our labours the most dangerous enemy to the depth of our still life hidden with Christ in God, and that every deed of apparent service which is not the real issue of living faith is powerless for good to others, and heavy with hurt to ourselves. Brethren and fathers in the ministry I how many of us know what it is to talk and toil away our early devotion; and all at once to discover that for years perhaps we have been preaching and labouring from mere habit and routine, like corpses galvanised into some ghastly and transient caricature of life. Christian men and women, beware lest this great enterprise of missions, which our fathers began from the holiest motives and in the simplest faith, should in our hand be wrenched away from its only true basis, and be done with languid expectation and more languid desires of success, from no higher motive than that we found it in existence, and have become accustomed to carry it on. If that be our reason, then we harm ourselves, and mask from our own sight our own unbelief. If that be the case the work may go on for a while, like a clock ticking with fainter and fainter beats for a minute after it has run down; but it will soon cease, and neither heaven nor earth will be much the poorer for its ending.
Again, the atmosphere of scornful disbelief which surrounded the disciples made their faith falter. It was too weak to sustain itself in the face of the consciousness that not a man in all that crowd believed in their power; and it melted away before the contempt of the scribes and the incredulous curiosity of the bystanders, without any reason except the subtle influence which the opinions and characters of those around us have on us all.
And, brethren, are not we in danger to-day of losing the firmness of our grasp on Christ, as our Saviour and the world's, from a precisely similar cause? We live in an atmosphere of hesitancy and doubt, of scornful rejection of His claims, of contemptuous disbelief in anything which a scalpel cannot cut. We cannot but be conscious that to hold by Jesus Christ as the Incarnate God, the supernatural Beginning of a new life, the sole Hope of the world, is to expose ourselves to the contempt of so-called advanced and liberal thinkers, and to be out of harmony with the prevailing set of opinions. The current of educated thought runs strongly against such beliefs, and I suppose that every thoughtful man among us feels that a great danger to our faith to-day comes from the force with which that current swings us round, and threatens to make some of us drag our anchors, and drift, and strike and go to pieces on the sands. For one man who is led by the sheer force of reason to yield to the intellectual grounds on which modern unbelief reposes, there are twenty who simply catch the infection in the atmosphere. They find that their early convictions have evaporated, they know not how; only that once the fleece was wet with dew and now it is dry. For unbelief has a contagious energy wholly independent of reason, no less than has faith, and affects multitudes who know nothing of its grounds, as the iceberg chills the summer air for leagues, and makes the sailors shiver long before they see its barren peaks.
Therefore, brethren, let us all take hood to ourselves, lest we suffer our grasp of our dear Lord's hand to relax for no better reason than because so many have left His side. To us all His pleading love, which knows how much we are moulded by the example of others, is saying, in view of the fashion of unbelief,' Will ye also go away?' Let us answer, with a clasp that clings the tighter for our danger of being sucked in by the strong current, Lord, to whom shall we go? Thou hast the words of eternal life.' We cannot help seeing that the creeping paralysis of hesitancy and doubt about even the power of Christ's name is stealing over portions of the Church, and stiffening the arm of its activity. Lips that once spoke with full confidence the words that cast out devils, mutter them now languidly with half-belief. Hearts that were once full of sympathy with the great purpose for which Christ died are growing cold to the work of preaching the Gospel to the heathen, because they are growing to doubt whether, after all, there is any Gospel at all. This icy breath, dear brethren, is blowing over our Churches and over our hearts. And wherever it reaches, there labour for Jesus and for men languishes, and we recoil baffled with unavailing exorcisms dying in our throats, and the rod of our power broken in our hands. Why could not we cast him out? Because of your unbelief.'
