Excellent point, Lockeliberty.
I think God's "one specific, universal purpose" is the clear reason Scripture exists in the first place. He's conveying to us a message about how we are to live and why we live. The fact that God speaks in poetry through Scripture is probably because everything God does is superlative.
Definition of Prose: Words in their best order.
Definition of Poetry: the BEST words in their best order.
But the essence of Scripture is not mystical, unknowable complexity; it is understanding. So while human poetry is dependent on the listener's reaction to it, God's poetry is singular in its intent and manifestation.
He wants us to "get it."
Beautiful!!!
On the how we are to live, I assert the importance of priorities: the Great Commandments, the Ten Commandments, the Sermon on the Mount.
Amen.
I guess I'd say He wants each of those who are His own, to get enough of it, individually and collectively, in order to bring about the harvest of His regenerate disciples. Prophesy may be the most glaring example of what we may know in part, here --especially prophesy yet unfulfilled, but we all only know in part at this point.
Yes, Ll, one explanation, yet one with a panoply of meaning and purposes inherent in the one.
Yes, marron, bb, it is not for us to exalt ourselves to either label God's Logos malleable metaphor, nor dried and brittle hyperdoctrine.
Yes, bb, A-G, the Logos is there in Creation too.
And how do we know these things? "The Bible tells me so."
The Logos Inscribed and the Logos made flesh are more defined, gainable knowledge to us, bb, than mere Creation without them. Wouldn't you say? --more able to be directly and fully related with and known. And the more important the relationship, the more it deals in specific communication --the more it comes by intent gaze and touch --by specified and focused concern, especially if self is to be shared. Especially so, when the sharing is between specific Creator and specifically Created.
