_First_, There is no presumption, from analogy, against the truth of it, upon account of its not being discoverable by reason or experience. Suppose one who never heard of revelation, of the most improved understanding, and acquainted with our whole system of natural philosophy and natural religion; such a one could not but be sensible, that it was but a very small part of the natural and moral system of the universe, which he was acquainted with. He could not but be sensible, that there must be innumerable things, in the dispensations of Providence past, in the invisible government over the world at present carrying on, and in what is to come; of which he was wholly ignorant,[161] and which could not be discovered without revelation. Whether the scheme of nature be, in the strictest sense, infinite or not; it is evidently vast, even beyond all possible imagination. And doubtless that part of it, which is open to our view, is but as a point in comparison of the whole plan of Providence, reaching throughout eternity past and future; in comparison of what is even now going on, in the remote parts of the boundless universe, nay, in comparison of the whole scheme of this world. And therefore, that things lie beyond the natural reach of our faculties, is no sort of presumption against the truth and reality of them; because it is certain, there are innumerable things, in the constitution and government of the universe, which are thus beyond the natural reach of our faculties. _Secondly_, Analogy raises no presumption against any of the things contained in this general doctrine of Scripture now mentioned, upon account of their being unlike the known course of nature. For there is no presumption at all from analogy, that the _whole_ course of things, or divine government naturally unknown to us, and _every thing_ in it, is like to any thing in that which is known; and therefore no peculiar presumption against any thing in the former, upon account of its being unlike to any thing in the latter. And in the constitution and natural government of the world, as well as in the moral government of it, we see things, in a great degree, unlike one another: and therefore ought not to wonder at such unlikeness between things visible and invisible. However, the scheme of Christianity is by no means entirely unlike the scheme of nature; as will appear in the following part of this treatise.
