(3.) If we compare the Scriptures with the imposture of Mahomet, in the book called the Alcoran, which the Turks make use of as a rule of faith, and prefer it to Scripture, and reckon it truly divine, that contains a system not only of fabulous, but corrupt and impure notions, accommodated to men’s sensual inclinations. Thus it allows of polygamy, and many impurities in this world, and promises to its votaries a sensual paradise in the next, all which is contrary to Scripture; so that composures merely human, whether they pretend to divine inspiration or not, discover themselves not to be the word of God, by their unholiness; as the Scripture manifests itself to be divine, by the purity of its doctrine; and indeed, it cannot be otherwise, considering the corruption of man’s nature, as well as the darkness and blindness of his mind, which, if it pretends to frame a rule of faith, it will be like himself, impure and unholy; but that which has such marks of holiness, as the Scripture has, appears to be inspired by a holy God.
Having considered the holiness of Scripture doctrines, we proceed to shew the weight of this argument, or how far it may be insisted on to prove its divine authority. It is to be confessed, that a book’s containing holy things or rules for a holy life, doth not of itself prove its divine original; for then other books might be called the word of God besides the Scripture, which is so called, not only as containing some rules that promote holiness, but as being the fountain of all true religion; and its being adapted above any book of human composure, to answer this end, affords an argument of some weight to prove it to be of God. For,
1. Man, who is prone to sin, naturally blinded and prejudiced against divine truth and holiness, could never compose a book that is so consonant to the divine perfections, and contains such a display of God’s glory, and is so adapted to make us holy.
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.
(2.) Men are much more liable to contradict one another when any scheme of doctrine is pretended to be laid down by different persons; for when they attempt to represent matters of fact, they often do it in a very different light: this may be more especially observed in those accounts that are given of doctrines that are new, or not well known by the world, or in historical accounts, not only of general occurrences, but of particular circumstances attending them, where trusting to their memory and judgment, they often impose on themselves and others.
(3.) This disagreement of human writings will more evidently appear, when their authors were men of no great natural wisdom, especially if they lived in different ages, or places remote from one another, and so could have no opportunity to consult one another, or compare their writings together; we shall scarce ever find a perfect harmony or agreement in such writings; neither should we in scripture, were it not written by divine inspiration.
