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! 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 heed 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.'
IV. Our faith can only be maintained by constant devotion and rigid self-denial.
I can touch but very lightly on that solemn thought in which our Lord sets forth the condition of our faith, and therefore of our power. This kind goeth not out but by prayer and fasting. The discipline then which nurtures faith is mainly moral and spiritual—not as a substitute for, or to the exclusion of, the intellectual discipline, which is presupposed, not neglected, in these words.
The first condition of the freshness and energy of faith is constant devotion. The attrition of the world wears it thin, the distractions of life draw it from its clinging hold on Christ, the very toil for Him is apt to entice our thoughts from out of the secret place of the most High into the busy arena of our strife. Therefore we have ever need to refresh the drooping flowers of the chaplet by bathing them in the Fountain of Life, to rise above all the fevered toil of earth to the calm heights where God dwells, and in still communion with Him to replenish our emptied vessels and fill our dimly burning lamps with His golden oil. The sister of the cumbered Martha is the contemplative Mary, who sits in silence at the Master's feet and lets His words sink into her soul; the closest friend of Peter the apostle of action is John the apostle of love. If our work is to be worthy, it must ever be freshened anew by our gaze into His face; if our communion with Him is to be deep, it must never be parted from outward service. Our Master has left us the example, in that, when the night fell and every man went to his own home, Jesus went to the Mount of Olives; and thence, after His night of prayer, came very early in the morning to the temple, and taught. The stream that is to flow broad and life-giving through many lands must have its hidden source high among the pure snows that cap the mount of God. The man that would work for God must live with God. It was from the height of transfiguration that He came, before whom the demon that baffled the disciples quailed and slunk away like a whipped hound. This kind goeth not out but by prayer.
The second condition is rigid self-denial. Fasting is the expression of the purpose to control the lower life, and to abstain from its delights in order that the life of the spirit may be strengthened. As to the outward fact, it is nothing—it may be practised or not. If it be, it will be valuable only in so far as it flows from and strengthens that purpose. And such vigorous subordination of all the lower powers, and abstinence from many an inferior good, both material and immaterial, is absolutely necessary if we are to have any wholesome strength of faith in our souls. In the recoil from the false asceticism of Roman Catholicism and Puritanism, has not this generation of the Church gone too far in the opposite direction? and in the true belief that Christianity can sanctify all joys, and ensure the harmonious development of all our powers, have we not been forgetting that hand and foot may cause us to stumble, and that we had better live maimed than die with all our limbs? There is a true asceticism, a discipline—a 'gymnastic unto godliness,' as Paul calls it. And if our faith is to grow high and bear rich clusters on the topmost boughs that look up to the sky, we must keep the wild lower shoots close nipped. Without rigid self-control and self-limitation, no vigorous faith.
And without them no effectual work! It is no holiday task to cast out devils. Self-indulgent men will never do it. Loose-braced, easy souls, that lie open to all the pleasurable influences of ordinary life, are no more fit for God's weapons than a reed for a lance, or a bit of flexible lead for a spear-point. The wood must be tough and compact, the metal hard and close-grained, out of which God makes His shafts. The brand that is to guide men through the darkness to their Father's home must glow with a pallor of consuming flame that purges its whole substance into light. This kind goeth not out but by prayer and fasting.
Dear brethren, what solemn rebuke these words have for us all! How they winnow our works of Christian activity! How they show us the hollowness of our services, the self-indulgence of our lives, the coldness of our devotion, the cowardice of our faith! How marvellous they make the fruits which God's great goodness has permitted us to see even from our doubting service! Let us turn to Him with fresh thankfulness that unto us, who are 'less than the least of all saints, is this grace given, that we should preach among the nations the unsearchable riches of Christ.' Let us not be driven from our confidence that we have a gospel to preach for all the world; but strong in the faith which rests on impregnable historical grounds, on our own experience of what Christ has done for us, and on nineteen centuries of growing power and unfolding wisdom, let us thankfully welcome all that modern thought may supply for the correction of errors in belief, in organisation, and in life, that may have gathered round His perfect and eternal gospel—being assured, as we have a right to be, that all will but lift higher the Name which is above every name, and set forth more plainly that Cross which is the true tree of life to all the families of men. Let us cast ourselves before Him with penitent confession, and say,—O Lord, our strength! we have not wrought any deliverance on earth; we have been weak when all Thy power was at our command; we have spoken Thy word as if it were an experiment and a peradventure whether it had might; we have let go Thy hand and lost Thy garment's hem from our slack grasp; we have been prayerless and self-indulgent. Therefore Thou hast put us to shame before our foes, and 'our enemies laugh among themselves. Thou that dwellest between the cherubim, shine forth; stir up Thy strength and come and save us!' Then will the last words that He spoke on earth ring out again from the throne: 'All power is given unto Me in heaven and in earth. Go ye therefore and teach all nations; and lo, I am with you alway, even unto the end of the world.'
