If...your assertion is correct...and God has elected all people for salvation...then...either God gets what He chooses...or human will is more powerful than God's will and humans break free of their salvation and overpower God.Yes, the elect are every one. God voted and elected all to be saved. Why would an individual not vote to accept that election? Because they as a sinner vote for themselves and against God's vote.
The work is not on getting saved. The work by humans is to constantly avoid salvation. No one is automatically saved. They are just automatically elected by God to be saved. Those who do give up their will, just end up being the ones elected that count.
Calvinist claim the Atonement was only for the elect, making the starting point narrow. What is even the point to think about salvation, if there literally is no choice in the matter?
Universalism is the teaching that no one is a sinner. Not that all humanity has been elected to be redeemed.
Since not every one knows they are elected, they need to hear about the Atonement. That is why the Gospel has to go out to all. Then those hearing can reject which does narrow down the end result.
Which one is it?
By your assertion these are the two views of God (theology) that you assert.
1) Universalism
2) Human will is superior,over and above God's will.
Universalism is that all humans have been atoned for by Jesus sacrifice (that is what you are claiming when you assert universal election).
You claim that the failure of God, and Christians, to preach the gospel to the "already elect" and the "already elect's" powerful will to reject God's election, makes them go to hell.
What you have asserted has literally zero support in the Bible. In other words, you have made a completely false assertion.
