If He’s God, He already know the future, what we call future isn’t the future to Him, it is history to Him, because the Bible says from everlasting to everlasting thou art God.
Time is an interruption on eternity, God lives in eternity, you live in time, time is a segment of eternity, so God is not bound by time, He doesn’t live in yesterday or tomorrow, He’s eternal, He’s not bound by time
Romans 8:29-30 NIV
For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters.
And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.
