According to the book "The Jesus Mysteries" they have proven through computer analyses that the later latter that have been attributed to Paul were not written by the same author as the earlier letters by Paul. Some of his latter letters were not added to the Canon until the 2nd or 3rd century. It all comes down to who was the "God" that decided what was inspired scriptures and what was not. It is a good book but that is all it is. It is no more inspired than any other book.

This won't relate well to any but anointed JWs, but it is just a point that some of us who actually believe everything in the Bible and are literalists have to deal with, which sort of affects the final canon. And that is that both Paul and John, the major contributors to the NT never were supposed to have died, but would live on throughout the ages until Jesus returned during the 20th century at the second coming. That's way too hard for some to believe but some of the anointed are actually aware of some of these surviving ancient ones. Obviously one advantage of having some of the first century original Christians survive is to "shepherd" the Bible until it got into a final stable form. I don't know of any historical direct interaction, but one would think that even by the 3rd century there might not have been much choice as far as the final Bible is concerned if there were many copies of the NT writings well distributed and considered by the body of the church as part of the original letters of Paul, etc. Of course, Paul was still alive and would have had that secretive influence. Additionally, just as God put certain persons in place in foreign governments to oversee Jewish matters (i.e. Joseph, Daniel, Nehemiah) this might have been the case as well until the Bible's canon became officially established, to at least include the books the original apostles wanted to include. Somehow three apocryphal books still got into the final canon (Esther, SOS and Ecclesiates) but they were not cross-quoted from by the NT Bible writers.
Thus under this theory, I can only imagine there us always present "sufficient influence" to make sure the Scriptures we know today as "The Bible" is essentially what was God's intended gift to us, mankind in general but particularly to those "anointed ones" who are custodians of God's light.
Satan, of course, would be desperate to create his own works to distract from the scriptures so one would suspect other writings, even of a pseudo-Biblical nature would show up and be promoted in later times by his followers -- so there's that too.
Interesting, but I suppose you have to have "faith" that the essential Bible is serving God's purpose. It's an amazing work and the Dead Sea Scrolls prove it is well preserved. At last the JWs do have a lot of good research on the Bible itself supporting it as a reliable copy of the original works.
Finally, if there appears any "serious" challenges to the current Bible, even perhaps well-faked "originals", is Paul and John had survived all this time then likely they would have perserved some of the ancient writings they thought would be necessary to preempt any real challeges, so there is that. That some of the really ancient original writings are still in position of some secretive Christian cultists that would dismiss any real challenge to scripture. I think the general "myth" about these writings are dealt with as part of the ppoular "Da Vinci Code" reference, that is, that along with the bloodline of Christ surviving, there are all these ancient writings that are supposed to be in existence and revealed at some point; the reference being that some of the original writings, even ancient genealogical records still exist and were preserved.
Now I understand if some think that Paul and John among others is too hard to believe, even though the Bible says they did, but one would think that the importance of these original writings would have been anticipated by Christians and some of the original writings kept secret and handed down and preserved apart from the primary church that would have become "apostate" early on as prophesied. The mere presence of these original writings would serve to keep the pagan influences in the church "honest" as far as the canon was concerned.
Interesting topic.
