But since it is foreknowledge, rather than God choosing, the men who reject Christ do so on their own volition and to their own doom.
It remains true then that “Whosoever will...” MEANS whoever will, not “Those I have chosen and secretly given life to...”
And we remain saved by grace thru faith rather than grace thru election.
“But since it is foreknowledge, rather than God choosing, the men who reject Christ do so on their own volition and to their own doom.”
According to what you are saying God is making an offer He knows is not valid to some since by foreknowledge or whatever, he knows that only certain ones will believe and therefore they are the ones to whom the offer is directed. The offer is useless to those God knows will not believe.
We are not questioning how they come to believe here but to whom the offer is directed. “Whosoever believeth...” must refer to those whom God knows will believe since God does not do useless things.
