Wk2-Q3: Bible Authority

A popular book says the Bible was never intended to be authoritative and describes it as a collection of stories. Do the following Scriptures support that?

All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness --2 Timothy 3:16 ESV

And we have something more sure, the prophetic word, to which you will do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts --2 Peter 1:19 ESV

Jesus’ high-priestly prayer:

Sanctify them in the truth; your word is truth. --John 17:17 ESV

Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth. --2 Timothy 2:15 ESV
