I take this to mean that you see man as the actor and God as the responder? What if that response means that God must change his mind and thus become mutable ?
The fact that He created us and knows what we will ask before we ask it changes the definition of everything only from HIS perspective. We are still freely choosing. From a human perspective -- as God designed that perspective to be -- we are in fact changing His mind.
I agree that from our human perspective we are making a choice that is absolutely free. But that choice is a part of the eternal plan of God .
My human example
A smart parent knows how to handle the growing independence of a child when they want to select their own clothes, so they do not walk around all "mismatched "
The parent selects a few "outfits" and presents them to the child to select from . The child believes she has selected her clothes, but in fact that selection was from a predetermined set of choices.
He hears the prayers of the righteous and answers them
I can trust the prayers of the righteous always reflect their desire to do as God wills. They will also see that the answer yes is not always Gods plan or will
Yet the bible also says God is "trustworthy". And He is. And I trust him completely. Yet I don't limit him. I know fellow believers who believe, and it is commonly taught in churches today that "God cannot do anything against his nature. Therefore God CAN'T sin, can't lie, can't you .... do things that aren't perfect".
See I don't believe that. I think the bible teaches that God spoke the universe into existence. He decided what was good and bad. He set up every rule and everything that is. I think God can do anything he please. I think he doesn't sin, or do those bad things because he chooses not to. I believe that he won't, not that he can't.
I believe that Jesus was fully God, and fully man. I think he had every opportunity to sin, and was tempted in ways that none of us have been tempted. And he didn't sin because he chose not to.
I'm trusting God. I'm believing in his promise. My hope is in his salvation. But you know, he doesn't owe me anything. It's his uinverse. I'm just blessed that he wants me.
I see man as responder, actor, responder, actor, responder! I see God as Actor, responder, acctor, responder, actor!!! It is highly significant that God is the first actor and the final actor. I do not disagree with your points about predestination for the most part. But that doesn't change, in my view, the fact that man is responding and that the action of man's response causes God to respond with action of His own. Thereby making both theologies true at the same time.
