Foreknowledge (or foreknown) isn't that God looks down some tunnel to see what people will do as many seem to believe. Rather foreknowledge is God deliberately purposes what He wants by His sovereign will and predestines that will. (He knows what He wants to do ahead of time (foreknown) and then He decrees it so (predestined).)
Pharaoh is a good example. God knew very well that Pharaoh wouldn't "chose" to let the people go until enough pressure had been put upon him. Yet God constantly asks him to. It is a puzzlement but this is what the scriptures teaches and we cannot understand the mind of God. Only that He is just and fair in all that He does. We just take the things that are revealed to us and rightfully understand the truth so we can understand God and His word.
Deuteronomy 29:29 “The secret things belong to the Lord our God, but the things revealed belong to us and to our sons forever, that we may observe all the words of this law.
Allow me also ask you this:
BEFORE the fall of mankind to sin, did Eve choose to eat of the tree of the knowledge of Good and Evil?
I have heard people say of sin, “The Devil made me do it”,
But I find it odd that some would say, “God made me do it”
