2. If we suppose that man could invent a collection of doctrines, that tended to promote holiness, could he invent doctrines so glorious, and so much adapted to this end, as these are? If he could, he that does this must either be a good or a bad man: if we suppose the former, he would never pretend the Scripture to be of divine authority, when it was his own composure; and if the latter, it is contrary to his character, as such, to endeavour to promote holiness; for then Satan’s kingdom must be divided against itself: but of this, more in its proper place, when we come to consider the character of the penmen of Scripture, to give a further proof of its divine authority. 3. It is plain, that the world without Scripture could not arrive to holiness; for the apostle says, 1 Cor. i. 21. _That the world by wisdom knew not God_; and certainly where there is no saving knowledge of God, there is no holiness; and the same apostle, Rom. i. 29, 30, 31. gives an account of the great abominations that were committed by the heathen; being destitute of Scripture light, they were _filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness, full of envy, murder, debate, deceit, malignity_, &c. If therefore the doctrines contained in Scriptures are not only pure and holy themselves, but tend to promote holiness in us, this is not without its proper weight to prove their divine original. III. The scriptures farther manifest themselves to be the word of God from the consent or harmony of all the parts thereof.[22] This argument will appear more strong and conclusive, if we compare them with other writings, in which there is but little harmony. Thus, if we consult the writings of most men uninspired, we shall find that their sentiments contained therein often times very widely differ; and if, as historians, they pretend to report matters of fact, their evidence, or report, does not, in all respects, agree together, which shews that they are fallible; but the exact and harmonious agreement of scripture proves it divine. That other writings of human composure agree not among themselves, is very evident; and it is less to be wondered at if we consider, (1.) That men are naturally blind and unacquainted with the things of God; and therefore their writings will hardly be consistent with themselves, much less with one another, as they are oftentimes inconsistent with the standard of truth, by which they are to be tried; nothing is more common than for men to betray their weakness, and cast a blemish on their composures, by contradicting themselves, especially if they are long, and consist of various subjects.
