Yes.
If you do not choose the jack, then it is clear that God's foreknowledge is faulty, broken, wrong. Since God's foreknowledge is not broken, then His knowledge is certain. He knows you will choose the jack.
Yes.
For all practical purposes, FROM THE STANDPOINT OF GOD, you have a deck of one card....the jack.
Wrong. You have invoked the modal fallacy again.
Are we getting anywhere or are we just going in circles? You've been more than patient and polite. We can continue if you wish, but if we're just spinning our wheels repeating ourselves, then the best course is probably to let it lie and come back to it some future day. What do you think?
Perhaps it is best to continue after you have read The Modal Fallacy. Also, real progress can be made if you come to see that truth and falsity do not imply one-card decks or impossibilities. "I like apples" is a true statement and it is an error to read this as "it is impossible for me to not like apples". See the question in #239.
