God's choosing not to know doesn't change anything relative to knowing.
Suppose it's possible for God to know someone's choice in advance.
God is always right (& so very smug about it).
Smug? Who has a better right to be smug when he encounters insects who all think they're geniuses?
Isaiah put man's existence in relation to his Creator into perspective when he wrote,
"Do you people not know? Do you not hear? Has it not been told to you from the outset? Have you not applied understanding from the foundations of the earth? There is One who is dwelling above the circle of the earth, the dwellers in which are as grasshoppers, the One who is stretching out the heavens just as a fine gauze, who spreads them out like a tent in which to dwell, the One who is reducing high officials to nothing, who has made the very judges of the earth as a mere unreality" (Isa 40:21-23)
How many grasshoppers are here telling God he's done it all wrong?
Seriously!
But suppose God chooses to not know the choice.
There is still this hidden choice which is knowable to him.
You've missed the point of God giving us the right of choice. It is WE who demonstrate by our actions what is in our hearts. We all have good intentions most of the time, but unless the good intentions translate into actions, what good are they really? It's not enough to talk the talk unless we are determined to walk the walk.
The devil says we can't love God that much, but God knows we can....Job proved it. If we bail, it is our own doing.
This choice is something already determined, ie, it has a single state, which God may at any time decide to learn.
Sure, he can know it....but do we? If we were judged on what God said we would do or not do, because he foreknew it, wouldn't we do what we have always done? Wouldn't we say "that's not fair, you didn't give me a chance to prove it"! Aren't we always the innocent ones in our own view? We can all move mountains in our own estimations, but when put to the test, how many will be left standing?
By our actions, not just our protestations, we have proved it to ourselves that God's judgment of us is correct....we blew it! The proof is right there in our own conduct.
Case closed your Honor.
Suppose a human made a choice which conflicted with the predetermined one.
This means that God would've been wrong if he had chosen to learn the choice in advance.
Can't have that!
That is not possible. Omniscience means that God can see into the future and the deed is as good as done....to him, but not to us. This is why God can prophesy accurately....it is history written in advance by a God to whom time means nothing.
He says he will not bring the current system to a conclusion until he has furnished due warning to "the entire inhabited earth" (Matt 24:14) Does that mean that he will sound a trumpet with fireworks and miracles so people will fall to their knees and obey him? NO! It will be the same scenario as when Noah walked the earth. People were given warning about what was going to happen, but it came from someone who was not like everyone else. He was different....very different, and he was doing something in preparation that made him look like the world's biggest nutter.
The people felt "smug" about disbelieving his warning....until the water began to swirl around their feet. It kept rising and how they must have wished that they had taken notice of him. That is the danger of judging something or someone in the court of public opinion. That same court tried and executed the son of God. It is not trustworthy.
That is the beauty of how God conducts his case....he allows everyone to be caught in the act of being themselves. He gives all humans the same instruction and allows their hearts to respond naturally. People weed themselves out of his purpose....he does not remove them until they are "dead" to him.
Do you understand this?
Omniscience & free will look incompatible.
Not a chance. :no:
