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
