I believe our choices are foreknown by God and that everything is predestined according to the choices God already know we're going to make. Do you equate omniscience with determinism? (I am avoiding the terms "foreknowledge" and "predestination" because they imply temporal conditions which don't apply to God).
I find your answer very interesting. If I am reading you correctly, you seem to be saying that "predestination" is nothing more than God's a priori sanction or affirmation of our future/not-yet-happened-but-foreknown choices.
Please correct me if I'm misunderstanding.
If all this is simply a matter of God's confirmation or endorsement of our choices, I don't see how this acknowledges God's absolute sovereignty any more than does the Arminian position.
At the risk of sounding like I'm passing the buck I would refer you to Dr. E's post #2890 below. I think she summed it up nicely.
But I would say this is more than "God's confirmation or endorsement of our choices". God's is not dependent on us or our "choices" to carry out His will. God is the driver who harden hearts and raise up prophets and is Himself actively involved in our lives.
This is a distinctly different view than the Arminian position which would say God's plan is dependent on us "evangelizing" the world. This is a much more hands-off approach.
