There is no Biblical warrant in the NT for "foreknowledge" referring to man's actions.
That is a notion of man interjected into the NT,
much like the notion of immaterial, non-physical is interjected into Paul's use of "spiritual," which never means immaterial in Paul, but always means of the realm of the Holy Spirit.
Foreknowledge simply means to know beforehand. You believe God knows man's actions beforehand, but then say that foreknowledge is not referring to man's actions.
Calvinism is a non-starter, God is love (1 John 4:16), who desires all to be saved (1 Timothy 2:4). Our God of love does not predestine any to eternal torment in order to receive glory for himself - as Calvin states, as shown below.
“…individuals are born, who are doomed from the womb to certain death, and are to glorify him by their destruction.” (John Calvin, Institutes of Christian Religion, Book 3, Chapter 23, Paragraph 6)
“…salvation is freely offered to some while others are barred from access to it.” (John Calvin, Institutes of Christian Religion, Book 3, Chapter 21, Paragraph 5)
“We call predestination God’s eternal decree, by which he compacted with himself what he willed to become of each man. For all are not created in equal condition; rather, eternal life is fore-ordained for some, eternal damnation for others.” (John Calvin, Institutes of Christian Religion, Book 3, Chapter 21, Paragraph 5)
Calvin say that what he teaches is dreadful - on this point I agree.
“Again I ask: whence does it happen that Adam’s fall irremediably involved so many peoples, together with their infant offspring, in eternal death unless because it so pleased God? The decree is dreadful indeed, I confess. Yet no one can deny that God foreknew what end man was to have before he created him, and consequently foreknew because he so ordained by his decree. And it ought not to seem absurd for me to say that God not only foresaw the fall of the first man, and in him the ruin of his descendants, but also meted it out in accordance with his own decision.” (John Calvin, Institutes of Christian Religion, Book 3, Chapter 23, Paragraph 7)
