III. If faith, then, be the witness and the exercise of our sonship in God, we can recognise at once the place it will hold among the other powers and capacities of our nature. We are so unfortunately apt to rank it as one among many faculties, and then to find ourselves engaged in agitating controversies concerning its limits and its claims. We have to secure for it, against the rest, a field for free dominion; and that field is hard to define; and rival powers beset it; and there are raids and skirmishes on every frontier; and reason is ever making violent incursions on the one side, and feeling is actively besieging it on the other: and the scientific frontiers, which we are ever on the point of fixing, shift, and change, and vanish, as soon as we determine them; and the whole force of Christian apologetics is spent in aimless and barren border-warfare.

But, if what we have been saying be true, the whole trouble turns on a mistake. Faith is not to be ranked by the side of the other faculties in a federation of rival powers, but is behind them all. It goes back to a deeper root; it springs from a more primitive and radical act of the central self than they. It belongs to that original spot of our being, where it adheres in God, and draws on divine resources. Out from that spot our powers divide, radiating into separate gifts,—will, memory, feeling, reason, imagination, affection; but all of them are but varying expressions of that essential sonship, which is their base. And all, therefore, run back into that home where faith abides, and works, and rises, and expands. At the root of all our capacities lies our sonship; at the root of all our conscious life lies faith, the witness of our sonship. By adherence in God, we put out our gifts, we exercise our functions, we develop our faculties; and faith, therefore, far from being their rival, whom they are interested in suspecting, and curbing, and confining within its limits, is the secret spring of their force, and the inspiration of their growth, and the assurance of their success. All our knowledge, for instance, relies upon our sonship; it starts with an act of faith[58]. We throw ourselves, with the confidence of children, upon an external world, which offers itself to our vision, to our touch, to our review, to our calculation, to our handling, to our use. Who can assure us of its reality, of its truth? We must measure it by those faculties under the manipulation of which it falls: but how can the faculties guarantee to us their own accuracy? How can we justify an extension of our own inner necessities to the world of outward things? How can we attribute to nature that rational and causative existence which we find ourselves forced to assume in it? Our justification, our confidence, all issue, in the last resort, from our sonship. Our powers have, in them, some likeness to those of God. If He be our Father, if we be made in His image, then, in our measure, we can rely upon it that we close with Nature in its reality; that our touch, our sight, our reason, have some hold on the actual life of things; that we see and know in some such manner, after our degree, as God Himself sees and knows. In unhesitating reliance upon our true sonship, we sally out and deal with the world; we act upon the sure conviction that we are not altogether outside the secret of objective existence. We refuse absolutely to doubt, or go behind the reports made to us by feeling, by memory, by thought. If once we are clear as to what the report is, we rest on it; we ask for no power to stand (as it were) outside our own experience, our own knowledge, so as to assure ourselves of their veracity. We are certain that our Father cannot have misguided us; that we are within His influence; that we are in modified possession of His truth; that our capacities reflect His mind. We could not have so confidently recognised, understood, and handled the world, if it had been wholly foreign to us. As it is, we lay instinctive hold upon it; we take spontaneous possession; we exert authority upon it; we feel our inherent right over it; we are at home in it; we move freely about it, as children in a father's house. Acting in this faith, all our capacities justify themselves to us; they respond to our reliance upon them; they develop into ever advancing strength under the motions of this trust; they form a continual and increasing witness to the verity of that sonship in which we have believed.

Faith, then, belongs to our entire body of activities. We live by faith. By faith, under the inspiration of faith, we put out our life, we set to work, we exercise faculties, we close with our opportunities, we have confidence in our environment, we respond to calls, we handle critical emergencies, we send out far abroad our experimental intelligence, we discover, we accumulate experiences, we build, and plant, and develop. An elemental act of faith lies at the root of all this advance; and every motion that we make, demands a renewal of that primitive venture. In all secular progress 'we walk by faith.' Every step revives the demand. Just as the earth, if it necessitates the idea of a primal creation, requires, by exactly the same necessity, an incessant renewal of that first creative act, so our life, if it required faith to start it, requires faith every moment to sustain it. Our faculties never arrive at a use which is self-dependent and self-originated, as if they could grow beyond the tentative conditions of their earliest assays. They originate in a venturous experiment; and, however long, and however complicated that experiment become, it retains its original character; it remains experimental to the end. The results, no doubt, justify the venture made; but, then, the first venture involved such immense assumptions, that no results reached can ever complete its justification, and so remove its tentative nature. For, by assuming a real correspondence between our faculties and the world with which they deal, it assumed that such a correspondence would never fail us; would be capable of infinite verification; would prove adequate to all possible experiences; would receive indefinite and progressive extension. No verifications ever reached can, then, exhaust the faith of that primitive venture; they can only serve to exhibit to it how far more was contained within that venture than it could ever have conceived. New knowledge, new experience, far from expunging the elements of faith, make ever fresh demands upon it; they constitute perpetual appeals to it to enlarge its trust, to expand its original audacity. And yet the very vastness of those demands serves to obscure and conceal their true character. This is the key to much of our present bewilderment. The worlds of knowledge and of action have assumed such huge proportions, have accumulated such immense and complicated resources, have gained such supreme confidence in their own stability, have pushed forward their successes with such startling power and rapidity, that we have lost count of their primal assumption. In amazement at their stupendous range, we are over-awed; we dare not challenge them with their hypothetical origin, or remind them that their entire and wonderful structure is but an empty and hollow dream, unless they are prepared to place their uttermost trust in an unverified act of faith. Given that trust, which relies on the reality of the bond which holds between our inner faculties and the outer world, then all this marvellous vision is rooted on a rock, has validity and substance. Withdraw that spiritual trust in our sonship, and all this fairy-world, won for us by science and experience,

These cloud-capped towers, these gorgeous palaces,

The solemn temples, the great globe itself,

Yea, all which it inherit, shall dissolve,

And, like an unsubstantial pageant faded,

Leave not a rack behind.

Our secular and scientific life is an immense experiment in faith,—an experiment which verifies itself by success, but which justifies itself only if it remembers to attribute all its success to the reality of that hidden relationship to God, which is the key to all its capacities, the justification of all its confidence, and the security of all its advance.

Such a remembrance is not easy for it: for the exercise of the capacities is instinctive and spontaneous, and it requires an effort of reflection to question the validity of such exercise. And such an effort seems tiresome and impertinent in the heat of successful progress, in the thick of crowding conquests. The practical man is apt to give an irritated stamp on the ground, which to him feels so solid, and to deem this a sufficient answer to the importunate inquiry how he knows that he has any substantial world to know and to handle. For faith lies behind our secular life, secreted within it: and the secular life, therefore, can go on as if no faith was wanted; it need not trouble its head with perplexing questions, whether its base be verifiable by the same standards and measures as its superstructure. Its own practical activity is complete and free, whether it discover its hidden principle or not: just as Mr. Jourdain's conversation was complete and free, long before he discovered that he was talking prose. We have to stand outside our secular life and reflect on it, to disclose its true spring. The appeal to faith here is indirect.
