The "All scripture is inspired by god..." quotation can't refer to anything in the new Testment. Why? Simply because it was almost a hundred years after Jesus that writings started to appear that referred to spoken stories about who said what to who.
The Apostles, Disciples, Jesus, Paul, etc. did not carry around bibles. Certainly there was no New Testament. There was no such thing as a portable Bible at all. The Septuagint version of the Hebrew scriptures (translated into Greek) would be the only thing Synagogue-attending Jews might be familiar with.
Having said that....
Saul/Paul wrote his letters after reportedly being blinded and hearing a voice. Those letters (epistles) were not holy scripture. They gradually acquired a certain important status until, eventually, (when they completely disappeared!) were regarded by the Catholic Church as HOLY WRIT!
Can you see where this is going?
Spoken stories eventually written down are different from eyewitness accounts made on the spot by trained reporters.
Do you imagine there were tape recorders at the Last Supper? Did people walk around with reams of papyrus or vellum and a sharpened quill and a supply of ink and enough candles to see what they were writing?
When the disciples ALL fell asleep in the Garden of Gethsemane and Jesus was praying his long prayer and weeping----WHO was standing there jotting it all down WORD-FOR-WORD? Hmmmm? Nobody.
Conversations constructed as "quotes" are mere literary inventions.
That is why we cannot hold people to a standard of Proof Text orthodoxy.
We do not and cannot ever know who said EXACTLY what to whom!
We can't prove anything about bible statements or even make certain what we do have corresponds to what was ORIGINALLY written.
Those texts, autograph originals are COMPLETELY GONE FOREVER!
Pause for a moment.
Ask yourself "why"?
Why would the most obviously important words ever spoken be allowed to vanish and be reconstructed by imperfect men?
Why would error-ridden copies of copies be circulated with no means of proofing them against originals?
The answer is very important.
Now take a look up above to the TOPIC QUESTION: If the bible is god's handbook for man, why is it such gobbletygook?
The answer is this:
Too many people with vastly different opinions have been mixed into a reconstructed soup that consists of part history, part myth, part legend, part fanciful imagination and part wishful thinking along with a heavy dose of genius and insanity!
Why WOULDN'T such a construction be gobbletygook?
What else could it possibly be?
