"Humans alone"? No, because it is "God-Breathed":
2 Timothy 3:16
"every Writing is
God-breathed, and profitable for teaching, for conviction, for setting aright, for instruction that is in righteousness,"
2 Timothy 3:16
"All scripture is given by
inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:"
(Emphasis Mine)
Humans have their own human-breathed writings that are quite powerful, gripping, and even profound.
And this is not surprising since all breath is ultimately of His Breath...without Him we can do nothing. This is why we cannot boast in what we have only received.
1 Corinthians 4:7
"7
For who makes you so superior? What do you have that you did not receive? And if you did receive it, why do you boast as though you did not?"
