You haven't made your understanding of election clear. It's not a matter of election/ no election. It's a matter of making your own understanding of election clear.
See post #2 here in this thread.
Are you asking how election negates free will? Or how election negates God's foreknowledge? IDK that. You tell me. I believe in God's predestination, God's election, God's foreknowledge AND man's freewill. I see no conflict with any if these doctrines. Now, when people start redefining any of these terms from how they are used Biblically, all kinds of conflicts creep in. Very similar to Timothy's situation he found himself in while suffering thru a bunch of people in his church started redefining words.
14 Remind them of these things, and charge them before God not to quarrel about
words, which does no good, but only ruins the hearers.
As for predestination and salvation:
8 Therefore do not be ashamed of the testimony about our Lord, nor of me his prisoner, but share in suffering for the gospel by the power of God, 9 who
saved [past tense] us and called us to a holy calling, not because of our works but because of
his own purpose and grace, which he gave us in Christ Jesus
before the ages began,10 and which now has been manifested through the appearing of our Savior Christ Jesus, who abolished death and brought life and immortality to light through the gospel, 11 for which I was appointed a preacher and apostle and teacher,12 which is why I suffer as I do.
As for OSAS:
But I am not ashamed, for I know whom I have believed, and
I am convinced that he is able to guard until that Day what has been entrusted to me.
