First of all, truth is aletheia. The unveiled reality lying at the basis of, and agreeing with, an appearance; the manifest or veritable essence of matter.
(That's lexicography from the preeminent first-language Greek scholar Spiros Zodhiates. But I'm sure you think your vague personal concept of your mind (device) is preferable to a Spirit-filled lifetime scholar, who spent his entire life devoted to the exacting presentation of the Greek text in English. He even did it from Erasmus' text exclusively. You know... the basis for the KJV.)
The above indicates that truth is the prosopon unveiling the reality of the hypostasis, which underlies the ousia (essence) of God.
Jesus Christ is the prosopon of the hypostasis of God, and God's hypostasis underlies His ousia. This is not only exegetical at a tremendous depth, but it's historical from Patristic writings of the same thing.
"Thy Word (Logos) is truth." That's because the Logos was God's divinity made flesh in the person (prosopon) of Christ. The prosopon unveiled the reality (hypostasis) of God, which underlies His essence.
Truth is the word that is founded upon God's very substance and essence as God. His Logos IS truth.
But you'll probably have some falsely over-simplified concept to administer as a test of faith, just you do with every scripture you post.
It's your gauntlet of works that you force everyone to run or you demean their faith as non-existent and them as unsaved.
You're always putting hoops out there for people to jump through, and then if someone puts out a hoop for you, you cry "works" at them.
His Logos is truth. Period. There is none other. Not yours or anyone else's. So to the extent that one speaks His Logos with their own logos, then and only then is there the word of truth.
