I certainly grant that many passages in the Scriptures are obscure and hard to elucidate, but that is due, not to the exalted nature of their subject, but to our own linguistic and grammatical ignorance; and it does not in any way prevent our knowing all the contents of Scripture. For what solemn truth can the Scriptures still be concealing, now that the seals are broken, the stone rolled away from the door of the tomb and that greatest of all mysteries brought to light—that Christ, God’s Son, became man, that God is Three in One, that Christ suffered for us, and will reign for ever? And are not these things known, and sung in our streets? Take Christ from the Scriptures—and what more will you find in them? You see, then that the entire content of the Scriptures has now been brought to light, even though some passages which contain unknown words remain obscure.
Thus it is unintelligent, and ungodly too, when you know that the contents of Scripture are as clear as can be, to pronounce them obscure on account of those few obscure words. If words are obscure in one place, they are clear in another. What God has so plainly declared to the world is in some parts of Scripture stated in plain words, while in other parts it still lies hidden under obscure words. But when something stands in broad daylight, and a mass of evidence for it is in broad daylight also, it does not matter whether there is any evidence for it in the dark. Who will maintain that the town fountain does not stand in the light because the people down some alley cannot see it, while everyone in the square can see it?
There is nothing, then, in your remark about the ‘Corycian cavern’; matters are not so in the Scriptures. The profoundest mysteries of the supreme Majesty are no more hidden away, but are now brought out of doors and displayed to public view. Christ has opened our understanding, that we might understand the Scriptures, and the Gospel is preached to every creature. ‘Their sound is gone out into all lands’ (Ps. 19.4). ‘All things that are written, are written for our instruction’ (Rom. 15.4). Again: ‘All Scripture is given by inspiration of God, and is profitable for instruction’ (2 Tim. 3.16)….
In a word: The perspicuity of Scripture is twofold, just as there is a double lack of light. The first is external, and relates to the ministry of the Word; the second concerns the knowledge of the heart. If you speak of internal perspicuity, the truth is that nobody who has not the Spirit of God sees a jot of what is in the Scriptures. All men have their hearts darkened, so that, even when they can discuss and quote all that is in Scripture, they do not understand or really know any of it. They do not believe in God, nor do they believe that they are God’s creatures, nor anything else—as Ps. 13* puts it, ‘The fool hath said in his heart, there is no God’ (Ps. 14:1). The Spirit is needed for the understanding of all Scripture and every part of Scripture. If, on the the other hand, you speak of external perspicuity, the position is that nothing whatsoever is left obscure or ambiguous, but all that is in the Scripture is through the Word brought forth into the clearest light and proclaimed to the whole world.
