In all trust in God there are two elements: a sense of need and of evil and weakness, and a confidence more or less unshaken and strong in Him, His love and power and all-sufficiency; and unless both of these two be in the heart, it is, in the nature of things, impossible, and will be impossible to all eternity, that purity and strength and peace and joy, and all the blessings which Christ delights to give to faith, should ever be ours.
Unbelief, distrust of Him, which separates us from Him and closes the heart fast against His grace, must cut us off from that which it does not feel that it needs, nor cares to receive; and must interpose a non-conducting medium between us and the electric influences of His might. When Christ was on earth, man's want of faith dammed back His miracle-working power, and paralysed His healing energy. How strange that paradox sounds at first hearing, which brings together Omnipotence and impotence, and makes men able to counter-work the loving power of Christ. 'He could there do no mighty work.' The Evangelist intends a paradox, for he uses two kindred words to express the inability and the mighty work; and we might paraphrase the saying so as to bring out the seeming contradiction: 'He there had no power to do any work of power.' The same awful, and in some sense mysterious, power of limiting and restraining the influx of His love belongs to unbelief still, whether it take the shape of active rejection, or only of careless, passive non-reception. For faith makes us partakers of divine power by the very necessity of the case, and that power can attach itself to nothing else. So, 'if thou canst believe, all things are possible to him that believeth.'
Still further, we may observe that there is involved here the principle that our faith determines the amount of our power. That is true in reference to our own individual religious life, and it is true in reference to special capacities for Christ's service. Let me say a word or two about each of these. They run into each other, of course, for the truest power of service is found in the depth and purity of our own personal religion, and on the other hand our individual Christian character will never be deep or pure unless we are working for the Master. Still, for our present purpose, these two inseparable aspects of the one Christian life may be separated in thought.
As to the former, then, the measure of my trust in Christ is the measure of all the rest of my Christian character. I shall have just as much purity, just as much peace, just as much wisdom or gentleness or love or courage or hope, as my faith is capable of taking up, and, so to speak, holding in solution. The 'point of saturation' in a man's soul, the quantity of God's grace which he is capable of absorbing, is accurately measured by his faith. How much do I trust God? That will settle how much I can take in of God.
So much as we believe, so much can we contain. So much as we can contain, so much shall we receive. And in the very act of receiving the 'portion of our Father's goods that falleth' to us, we shall feel that there is a boundless additional portion ready to come as soon as we are ready for it, and thereby we shall be driven to larger desires and a wider opening of the lap of faith, which will ever be answered by 'good measure, pressed together and running over, measured into our bosoms.' But there will be no waste by the bestowment of what we cannot take. 'According to your faith, be it unto you.' That is the accurate thermometer which measures the temperature of our spiritual state. It is like the steam-gauge outside the boiler, which tells to a fraction the pressure of steam within, and so the power which can at the moment be exerted.
May I make a very simple, close personal application of this thought? We have as much religious life as we desire; that is, we have as much as our faith can take. There is the reason why such hosts of so-called Christians have such poor, feeble Christianity. We dare not say of any, 'They have a name to live, and are dead.' There is only one Eye who can tell when the heart has ceased to beat. But we may say that there are a mournful number of people who call themselves Christians, who look so like dead that no eye but Christ's can tell the difference. They are in a syncope that will be death soon, unless some mighty power rouse them.
And then, how many more of us there are, not so bad as that, but still feeble and languid, whose Christian history is a history of weakness, while God's power is open before us, of starving in the midst of abundance, broken only by moments of firmer faith, and so of larger, happier possession, that make the poverty-stricken ordinary days appear ten times more poverty-stricken. The channel lies dry, a waste chaos of white stones and driftwood for long months, and only for an hour or two after the clouds have burst on the mountains does the stream fill it from bank to bank. Do not many of us remember moments of a far deeper and more earnest trust in Christ than marks our ordinary days? If such moments were continuous, should not we be the happy possessors of beauties of character and spiritual power, such as would put our present selves utterly to shame? And why are they not continuous? Why are our possessions in God so small, our power so weak? Dear friends! 'ye are not straitened in yourselves.' The only reason for defective spiritual progress and character is defective faith.
Then look at this same principle as it affects our faculties for Christian service. There, too, it is true that all things are possible to him that believeth. The saying had an application to the disciples who stood by, half-ashamed and half-surprised at their failure to cast out the demon, as well as to the father in his agony of desire and doubt. For them it meant that the measure of Christian service was mainly determined by the measure of their faith. It would scarcely be an exaggeration to say that in Christ's service a man can do pretty nearly what he believes he can do, if his confidence is built, not on himself, but on Christ.
If those nine Apostles, waiting there for their Master, had thought they could cast out the devil from the boy, do you not think that they could have done it? I do not mean to say that rash presumption, undertaking in levity and self-confidence unsuitable kinds of work, will be honoured with success. But I do mean to say that, in the line of our manifest duty, the extent to which we can do Christ's work is very much the extent to which we believe, in dependence on Him, that we can do it. If we once make up our minds that we shall do a certain thing by Christ's help and for His sake, in ninety cases out of a hundred the expectation will fulfil itself, and we shall do it. 'Why could not we cast him out?' They need not have asked the question. 'Why could not you cast him out? Why, because you did not think you could, and with your timid attempt, making an experiment which you were not sure would succeed, provoked the failure which you feared.' The Church has never believed enough in its Christ-given power to cast out demons. We have never been confident enough that the victory was in our hands if we knew how to use our powers.
The same thing is true of each one of us. Audacity and presumption are humility and moderation, if only we feel that 'our sufficiency is of God.' 'I can do all things' is the language of simple soberness, if we go on to say 'through Christ which strengthened me.'
