As with a lot of things in scripture...you can know something intellectually and not "know" it.
From my earliest memories omniscience has been taught. As a trivia question I've always known the answer. Actually understanding the fulness of that and how my own limited mind is unable to grasp that and the whole faith element commingled in the equation that is being human...I cannot say that I fully "know". I can say that I ponder it often enough and intellectually I reach impasses that I won't share but will respond to if someone has a difficulty finding symbiosis after such a fashion.
For me there's a lot of different ways to "know" something. There's also a lot of different "levels" of how deep our "know" really is.
When I was very young I "knew" a lot of things about the Lord because the word told me so, but that was almost like a "looking forward" sort of knowledge. As I see things play out personally and am embroiled in ways where it's a battle to rest in that knowledge despite opposition, it becomes a little more "real". So I could say I "know" a bit deeper today than I did, and I still have a connection to those early memories which helps me to know I've grown in that knowledge/faith/wisdom.
This may not be making sense at all but I look forward to faith being made sight. The scripture about going from glory to glory is on my mind but I can't pinpoint it specifically so if someone knows it and would like to share...it seems succinct.
I see myself somewhere in the middle. My memory is my own beginning, where I am now in life is my middle, death will be the end but this is merely the beginning...puzzled yet? I am, but I'm content to rest in the mystery of it at present.
I can say that the more he knows me and shows me and grows me the more cosmic omniscience matters less. Foreknowledge makes some sense, but compartmentalizing this attribute of the Lord is practically impossible as I don't think it can reasonably fit in a compartment. I don't understand omniscience so I just let it go, I don't think we really can except to know that it is and HE is. Each day it makes a little bit more sense but somehow less at the same time. Perhaps, the conclusions that matter are made, and the pointless meandering by a limited being occur less and less frequently?
