How do we know the Bible is true?

Scripture thus proved will be its own best evidence as a Divine revelation. No doubt there is abundance of external witness to its truth; but the surest of all is its own direct testimony to man's heart and conscience. Without Scripture he is an enigma which his own wit cannot explain: he knows not from whence he came or whither he is going; he knows neither himself nor God. With Scripture, "light is come into the world;" and what makes all things manifest needs not, although it everywhere finds, a testimony outside itself. Truth speaks for itself — "commends itself to every man's conscience in the sight of God" — although the true it is who alone will hear it.

We rise from our task. This brief survey of Scripture has only served to deepen in the writer’s mind the truth of the inspiration of the Scriptures, and how they should be treated with the utmost reverence, realising that God Himself is speaking to us in them. We have brought forward very little, but that little overwhelmingly proves that the Scriptures are all that they themselves claim to be. The claim has been amply substantiated by the contents of the Book, the character of its writers; the fulfilment of prophecy; the correspondence between the shadows of the ceremonial law and their fulfilment in Christ and His atoning death on the cross; the supreme Person of our Lord, as delineated in the four gospels, the presentation of a life unique in every way, and in character and degree infinitely beyond every other life, however exalted, and finally its living power in moulding human lives for God. By its fruits we know the Book to be supremely good.

The Bible is the only book that faithfully tells us what we are, and that even to the discerning of the thoughts and intents of the heart. This shows it to be divine, for God only searches the heart. It also truly reveals God, so that when the word is received, it brings our souls into the consciousness of God having to do with us. This also shows its divinity, for "the world by wisdom knows not God." The variety of aspects in which the Son who came forth from the Father to save sinners is presented to us ― His personal glory, moral perfectness, finished work, walk, words, ways, life, death, resurrection, ascension, glorification, present offices, and future judgments and reign ― as the leading truths of scripture, give it also a divine character. Its unity, too, carries with it the stamp of divinity as nothing else could. The way in which the different parts are adapted to each other; types in the Old Testament having their antitypes in the New; a multitude of prophetic statements in the former having their accomplishment in the latter, and the immense number of quotations in the New from the Old Testament, to prove the soundness of the doctrines taught, combine to give it a divine character which is incontestable. It is not then surprising that an inspired writer should commend "the word" to us as if in its operations it possessed divine attributes. "The word of God is quick and powerful and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." (Heb. 4:12.)

From all these various witnesses, we not only learn that God had ordered writing as a means of communicating His mind and will, but, as a fact, we also find preserved for us in a most marvellous way for nearly two thousand years a number of books written by various persons who had no communication with each other; written, too, at different times, and under different circumstances for a period extending over 1500 years, and all the books so agreeing together that a spiritual mind can trace all as being under the guidance of a master mind: books that were valued by other prophets, treasured up by faithful men, esteemed by many as of more value than thousands of gold and silver, and ministering words which were found and eaten to the joy and rejoicing of the heart. In these many books we find the prophetic words of some afterwards registered by others as fulfilled, and warnings unheeded, too, meeting with the predicted judgments; the depravity and utter ruin and wickedness of man set forth, and alas, manifested, while the nature of God, as love and light, His attributes and words of holiness, grace and truth, stand out in all their uncompromising perfection, and eternal excellence. Because of these things, the written word of the Old Testament brings such conviction to the soul of its divinity and eternal truth, when opened up and brought home by the Spirit, that the heart no more looks to men's opinions, or other external evidence, than a child, when gazing with delight on a photograph of his living mother, would inquire who it is.

There are evidences, on every hand, many and varied and of the very best; evidences both direct and indirect. The world is full of them, and they may be seen every day; museums of antiquity contain them; evidences of the Bible's veracity are writ large on Egyptian and Assyrian monuments and temples; the ruins of buried cities and the tombs of forgotten kings abound with them, even mummies bearing mute testimony to what the "scripture of truth" declares; and the spade of the excavator brings to light fresh witnesses every year. The natural sciences, astronomy, geology, physiology, anatomy, including even that most exact of all sciences, mathematics, all bear united and harmonious witness to the truth of Scripture, written with "the finger of God."

If Scripture had been framed on a lie, this could not have been sustained in perfect consistency throughout the writings of the inspired penmen. Slips, inconsistencies contradictions would have occurred. Yet not one inconsistency can be discovered, however microscopically the Scriptures are examined. This is most convincing.

IN THE OPENING verses Luke avows the object before him in writing his Gospel; he wished to bring certainty to the mind of a certain Gentile convert. God had given him a perfect understanding of all things from the outset, so now he wrote them "in order," or "with method;" and we shall see as we proceed that he sometimes ignores historical order to present things in a method that is moral and spiritual. The understanding of that moral and spiritual order, together with having the facts clearly in writing, would bring certainty to Theophilus, as also it will to us. We see here how certainty is linked with the Holy Writings — the Word of God. If we had not the Holy Writings, we should have certainty of nothing.

But this is not all. Whilst there are notable phrases and words common to all,6 there are quite as notable differences7 in the mode of communication. Hence speculative minds are tempted to irreverent cutting of the knot they cannot untie;8 whilst unexercised souls fail to gather the profit intended of the Spirit through every shade of difference. For it is a perversion of the truth that the writers were inspired, but not the writings. If 2 Peter 1:21 warrants the former, still more explicit and distinctly applicable is the claim for the latter in 2 Tim. 3:16. In the verse preceding we have the "sacred" title of the Old Testament; but in verse 16 the Spirit of God pronounces for "every" thing that falls under the designation of "Scripture." It is not a question of human infirmity, but of God's power. Every Scripture is inspired by God (θεόπνευστος). Not only were the men inspired, but so, according to the Apostle Paul, is the result. Ordinarily their writing, like their words, would have been liable to the imperfections of human speech and the limitations of human thought; but every Scripture, every writing that comes under this category, is God-breathed, and in no way "left" to the mere accidents of human faculties. To mix up with inspiration the manifold errors of copyists in the lapse of ages is illicit and illogical, not to say dishonest, for this is quite another question. All we contend for is the Divine character of indisputable Scripture.

Now here we learn that "prophecy was not ever uttered by the will of man, but holy men of God spake under the power of the Holy Spirit". This is one of the passages about the inspiration of the Word of God. Those who wrote the books of the Bible were holy men of God, acknowledged by Him as His instruments. Moses was such a man of God (Psa.90:1), just as Elijah, who could say, "The Lord ..., before whom I stand" (1 Ki.17:1). They stood before God, conscious of the fact that He constantly looked upon them. "Holy men of God", that is the character of those who wrote the books of the Old Testament - and also of the New Testament. But that is not all. Although believers in Old Testament times did not possess the Holy Spirit as we do, yet the holy writers were led by Him; they wrote in the power of the Holy Spirit. So what they penned were not human ideas, but things given to them by the power of the Holy Spirit.

It is truly refreshing to transcribe such lines from the pen of one who has been a profound student of scripture for forty years. They are of unspeakable value, of a moment when so many are ready to cast a slight upon the sacred volume. Not that we are, in any wise, dependent upon human testimony in forming our conclusions as to the divine origin of the Bible, inasmuch as these conclusions rest upon a foundation furnished by the Bible itself. God's word, as well as His work, speaks for itself; it carries its own credentials with it; it speaks to the heart; it reaches down to the great moral roots of our being; it penetrates the very innermost chambers of the soul; it shows us what we are; it speaks to us as no other book can speak; and, as the woman of Sychar argued that Jesus must be the Christ because He told her all things that ever she did, so may we say in reference to the Bible, It tells us all that ever we did, is not this the word of God? No doubt it is only by the Spirit's teaching that we can discern and appreciate the evidence and credentials with which holy scripture presents itself before us; but still it does speak for itself, and needs not human testimony to make it of value to the soul. We should no more think of having our faith in the Bible established upon man's testimony in its favour than we should think of having it shaken by his testimony against it.
