Wow, Droopy, that was pretty well said!
A couple of other things occur to me: First,
Doctrine and Covenants 1:24 Behold, I am God and have spoken it; these commandments are of me, and were given unto my servants in their weakness, after the manner of their language, that they might come to understanding.
Altho I've seen some very accurate things in the scriptures, I'm not sure the Lord always speaks in mathematically precise equations, but rather, we have to understand what's meant - even in the modern revelations. Treating the ancient scriptures in an overly pedantic fashion will not address the truth of them. The guys that wrote them talked and wrote in a style that requires comprehension of what they were intending. Therefore, it's often counterproductive to split hairs.
Second, regarding the Spirit and understanding the scriptures: this was directed at Oliver Cowdery:
Doctrine and Covenants 18:2-4
2 Behold, I have manifested unto you, by my Spirit in many instances, that the things which you have written are true; wherefore you know that they are true.
3 And if you know that they are true, behold, I give unto you a commandment, that you rely upon the things which are written;
4 For in them are all things written concerning the foundation of my church, my gospel, and my rock.
"The things which you have written" meant the Book of Mormon. We can surmise that by "the things which are written" the Lord meant the Book of Mormon and other scriptures, which at that time was the Bible. At this time, that was the main corpus of extant written scripture.
So from this we learn that the Holy Spirit does show that various things in the writings are true, and once he shows this to someone, they should rely on those things. Note that this does not give a blanket endorsement of the entire Book of Mormon and the Bible, but only those things witnessed by the Holy Spirit.
I will illustrate with a story. Suppose you are struggling with financial woes and having to change place of residence and also there are family problems and car problems. (Can anybody relate?) You are reading in the scriptures and suddenly part of it seems to stand out at you, like this:
And when the ship was caught, and could not bear up into the wind, we let her drive. And running under a certain island which is called Clauda, we had much work to come by the boat: Which when they had taken up, they used helps, undergirding the ship; and, fearing lest they should fall into the quicksands, strake sail, and so were driven. And we being exceedingly tossed with a tempest, the next day they lightened the ship; And the third day we cast out with our own hands the tackling of the ship. And when neither sun nor stars in many days appeared, and no small tempest lay on us, all hope that we should be saved was then taken away. But after long abstinence Paul stood forth in the midst of them, and said, Sirs, ye should have hearkened unto me, and not have loosed from Crete, and to have gained this harm and loss. And now I exhort you...
The words "ye should have hearkened unto me" seem to be almost standing out from the rest of the page. You realize that the Lord is speaking directly to you,
thru the written word. It's the Holy Ghost that makes this happen.
This follows the pattern given in DC 18:2-4; the Holy Spirit has manifested that something in the scriptures is true, and you should rely on it. The rest of the passage from Acts, while thrilling, isn't in the same lofty category.
I believe that this is what is meant by scripture: those parts of the text that are "highlighted" by the Holy Spirit.
The Bible and the Book of Mormon have many passages that are just recountings of things that happened; this cannot be what's meant by the Word of God, or scripture.
