“The Spirit is the one who testifies, because the Spirit is truth.”
“The Spirit of truth … proceeds from the Father.”
“I am … truth.”
It is correct to say that the triune God reliably tells the truth [Gk: alētheuō] and that he always speaks truly
[alēthōs]. He is both accurate and ingenuous.
And yet despite their aptness, these statements are not sufficient. They fall short. Scripture makes such claims repeatedly, but that is not all it says.
The doctrine of God’s veracity and reliability does not turn on verbs and adverbs.
