First, let me say that I do not believe that the Bible in any of its forms is the "Word of God". The intention of my initial post was to show that the WTS says that only the initial writing was "inspired of God" and these writings are no longer available, and that the WTS says that the Bible we now have is not inspired. I also wanted to indicate that the NT writers quoted from the range of sources, many of which are not available today.
I did not mention that the NT writers quoted from sources that are today considered to be apocryphal (1 Enoch, etc., etc., etc.).
In my desire to keep focused, I did not mention "canon" -- that is, the list(s) of writings which are considered sacred scripture. There is no list of universally accepted books. The idea of a Canon was initiated by Christians, likely motivated by moving from scrolls to the codex format. The Christians took several centuries to set upon a canon, with only the Catholic Church voting on the matter in the 15th century. Protestants have never taken a vote on the canon, accepting it by Tradition.
The formation of a canon by the Jews is shrouded in mystery. It certainly evolved during the centuries of the Common Era (CE). Canonisation is a Christian idea.
There is any number of canons, as demonstrated, with one example, through the Tanakh and the Protestant versions. (See also the Catholic version, Orthodox versions, plus many others).
Many theologians speculate that the canon should be revisited, while at the same time acknowledging that each community operates from a "canon within a canon". We can see this in the limited range of passages considered by the WTS, SDA, etc., etc.
An interesting book by an evangelical Christian is: "A High View of Scripture?" by Craig D. Allert.
