I think you need to read what I said again.
He knows who He will save. (Comment: He knew this before creation).
He knows who will reject him. (Comment: Again, He knew this before creation).
And He also empowered the spiritually dead/spiritually enslaved people to respond with a gift of faith...all acts of initiation and power on the divine side...By God choosing Israel, guess what? He thereby
failed to choose/elect the surrounding nations & tribes. (For some reason, we don't seem to hear people railing about that as being a bit "narrow")
Knowledge is one thing; empowerment is another.
