Now, was not faith the power of life in every man, no man could live by faith, nor could it be the principle or power of life in any man. But seeing every man, whether earthly or heavenly, is that which he is, by faith; and faith will and must have its work in every man; and he cannot live without it, or free from it; hence is the absolute necessity of the one right faith, in order to salvation, and the impossibility of anything else to avail in the stead of it. Thence also it is, that Christianity applies not to the reason of any man, because reason is not the principle of life, or the former of it; but it calls the heart to a right faith, because man is only lost and separate from God and heaven by his faith in the things and powers of this world. And therefore all salvation does, and only can, arise from a faith turned to God; and also all damnation from faith in the things of this world. And no man can turn either to God, or to this world, but by faith; that is, by giving up himself either to the one, or the other; which is the highest act or power of faith. For there is nothing that works either to life or death, in any man, but that to which he is given up, by faith in it. And reason never had, nor ever can have, or do, anything else, but one and the same underwork, or office, let faith take which way it will.
