The Bible is inspired, but is it Complete?

In the eighth Article of Faith of the Church of Jesus Christ of Latter-day Saints, we read:

We believe the Bible to be the word of God as far as it is translated correctly...Many other Christian and Jewish religions have a problem with that statement, considering it to be a perfect work of art. The LDS perspective is that it was correct upon being received by the prophet(s) from the Lord, but through the centuries of translation and copying, things have been changed or lost.

The Book of Mormon explains it this way in a revelation Nephi had concerning the Bible:

And the angel of the Lord said unto me: Thou hast beheld that the book proceeded forth from the mouth of a Jew; and when it proceeded forth fromthe mouth of a Jew it contained the fulness of the gospel of the Lord, of whom the twelve apostles bear record....Wherefore, these things go forth from the Jews in purity unto the Gentiles, according to the truth which is in God.  And after they go forth...unto the Gentiles....that there are many plain and precious things  taken away from the book, which is the book of the Lamb of God. And after these plain and precious things were taken away it goeth forth unto all the nations of the Gentiles.... (1 Nephi 13:24-29).Things lost from the Bible? Can we name any? Here are a few:

1) The picture shown here is of the papyrus fragment of 1 Samuel, chapter 11, from the Dead Sea Scrolls (4QSama), dating 2000 years ago. It is the oldest copy of Samuel in existence. The fragment is not found in any other copy of Samuel, but is mentioned by Josephus. The new information answers a long-unsolved mystery in the chapter: just why did the Ammonite king Nahash cause the eyes of the Israelites in Nabesh-Gilead to be gouged out after they surrendered peacefully?  "4QSama explains that Nahash reserved this particular punishment for men he considered rebels, some of whom had earlier taken shelter in Jabesh-Gilead."  (Biblical Archaeological Review, July/August 1997, pg 29).

2) The Bible mentions several books that are no longer in the collection known as the Bible (which has gone through several peer reviews over the millenia, the last and current collection being done by St Jerome). Some of these books, or fragments of them are quoted in the Bible and many are available today:  

Book of the Covenant (Ex. 24:7); Book of the Wars of the Lord (Num. 21: 14); Book of Jasher (Josh. 10: 13); Book of the Statutes (1 Sam. 10:25); Book of Enoch (Jude 14); Book of the Acts of Solomon (1 Kgs. 11:41); Book of Nathan the Prophet, and that of Gad the Seer (1 Chr. 29:29); Book of Ahijah the Shilonite, and visions of Iddo the Seer (2 Chr. 9:29); Book of Shemaiah (2 Chr. 12:15); Story of the Prophet Iddo (2 Chr. 13:22); Book of Jehu (2 Chr. 20:34); the Acts of Uzziah, by Isaiah, the son of Amoz (2 Chr. 26:22); Sayings of the Seers (2 Chr. 33:19); a missing epistle of Paul to the Corinthians (1 Cor. 5:9); a missing epistle to the Ephesians (Eph. 3:3); missing epistle to the Colossians, written from Laodicea (Col. 4:16); a missing epistle of Jude (Jude 3). 
In fact, the current fragments of the Book of Enoch are quoted in the Bible over 30 times. And this is not to mention a plethora of books that may or may not belong in the Bible but are compiled today in books like: The Lost Books of the Bible and the Forgotten Books of Eden or the Dead Sea Scrolls.3) Noted here is the following quote about the Bible: "The Hebrew Bible was, to some extent, a fluid document-changing from generation to generation because of scribal errors or editorial privilege."   (Biblical Archaeological Review, July/August 1997, pg 29).

So, we can see from historical evidence, that the Bible has gone through tremendous changes, and although it is very inspired and much is translated correctly, there still are things missing from it. For this reason, Latter-day Saints give thanks for modern prophets and apostles who receive revelation from God, giving us knowledge of lost truths (like the Book of Mormon,and of things to come.
