That's not really foreknowledge, that's just knowing what possible choices there are. Using that definition, the flight attendant that served me lunch last week knew all possible outcomes as well.
No, you must need to read what Middle Knowledge is. It is knowing all the choice and options and knowing the OUTCOME of them all. This is spoken of as the knowledge of counterfactuals.
William Lane Craig calls Molinism “one of the most fruitful theological ideas ever conceived. For it would serve to explain not only God’s knowledge of the future, but divine providence and predestination as well”. Under it, God retains a measure of divine providence without hindering man's freedom. Because God has middle knowledge, He knows what an agent will freely do in a particular situation. So, agent A, when placed in circumstance C, will freely choose option X over option Y.
Paul in Romans 8:29 says: ""For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren."
Romans 9 is a proof that shows God's foreknowledge of Jacob and Esau. Jacob and Esau were foreknown before they had ever done anything either good or bad.
Again, I suppose I don't know the Bible and am twisting it. But the entire chapter of Psalm 139 deals with foreknowledge of us personally. He knows us better than we could ever know each other. So our comparisson of knowing our children and knowing what they will do...is really no comparison. God knows the number of hairs on our heads, and knows the words that we will speak before we speak them. Job 42:2 says that God can do everything. No thought can be withheld from Him.
Using the Bible, one cannot show that God does not have foreknowledge. Romans 8:29, Romans 11:2, and 1Peter 1:20 speaks of God's foreknowledge of people and wo they would become. Acts 2:23 says that Jesus was delivered up according to the foreknowledge of God. 1Peter 1:2 speaks of those that were chosen because God had foreknowledge of them. 1John 3:20 says that God knows our hearts and in fact knows EVERYTHING. Note the word everything. There is nothing that God does not know.
