If God is omnipotent and beyond the bounds of time, then humans cannot have free will.
One response I have seen to this statement is that God's omniscience does not include knowing with 100% certainty what our free will choices will be in the future. However, a timeless (beyond the bounds of time) God effectively does know our free will choices before we make them.
Think of our universe as a book that God has opened to page number 2017. While it takes us 1 year for God to flip to the next page, it takes exactly 0 seconds of God's time. After all, he is omnipotent and timeless. If it took him even a fraction of a millisecond, then he would indeed be constrained by some kind of time. (It would beg the question of who constrained God with time, yadda yadda yadda...)
Being omnipotent, God has the power to jump forward and backward in the book at his leisure and rewrite things along the way. Granted, rarely does he affect our free will. (For example, there was one instant where a pharaoh was going to release the enslaved Jews, but God decided to harden his heart and then punish the firstborn sons of Egypt.) Obviously, the bible doesn't discuss God jumping forward and backward in time because it is written as the one timeline that actually occurred and is actually occurring.
Therefore, although God may change something in the intro section of the book (we generally call them the BCE section), he can flip forward at any moment to see how it all plays out without affecting our free will choices (except for the pharaoh's and perhaps anyone he has revealed himself to along the way). In fact, "moment" is the wrong word because it is instantaneous for God. Indeed, while making any revisions to the book, God instantly knows how every future page will play out because it takes him zero time to flip the pages of the book.
In summary, just as many Christians have stated time and time again, everything plays out in God's master plan. Our supposedly free will choices have been affected by God's writing and revisions to the book to ensure that the book reads exactly as God wants and, therefore, are not really free will choices at all.
