To the contrary, I heartily receive the words of God which includes of course Jesus' words and those the Holy Spirit caused to be written.
God's people know His voice when we hear it:
But he that entereth in by the door is the shepherd of the sheep. To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. - John 10:2-6
God's words are alive in us - they are not like the words of men. (I Cor 2, Romans 8, et al) His words are self-authenticating and apparent to us who hear Him.
No doubt those who compiled or maintained the Scriptures over thousands of years - whether Jew or Christian - knew His voice and followed His leading:
The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times. Thou shalt keep them, O LORD, thou shalt preserve them from this generation for ever. - Psalms 12:6-7
The people Jesus is speaking to in the following passage were physically hearing Him (pressure or sound waves) but they could not spiritually hear Him. They did not have "ears to hear:"
Why do ye not understand my speech? even because ye cannot hear my word. - John 8:43
Again, Scriptures contain the words of God, we know this - their authority and authenticity - because we know His voice when we hear it.
I spent the first 20+ years of my life without Salvation. I can recall how reading the Bible was like reading The Canterbury Tales in Olde English ... almost unintelligible, a chore not eagerly undertaken. BUT, when I was Born Again, the Bible has come alive to my inner man. The volume of meaning in scripture is like food when I’m hungry.
