Because you do not understand what Paul is talking about in Ephesians.
I had the same problem with you in Romans.
Your noticing key phrases and sentences in certain letters but missing, what Paul is actually saying.
Ephesians 2:11-12
Therefore remember that formerly you, the Gentiles in the flesh, who are called Uncircumcision by the
so-called Circumcision, which is performed in the flesh by human hands, remember that you were at that
time separate from Christ, excluded from the commonwealth of Israel, and strangers to the covenants of
promise, having no hope and without God in the world.
This paragraph is a corporate letter directed to the Gentiles.
The Gentiles were not chosen, elect, set apart, for anything other than destruction.
What do you think "no hope" or "without God" means?
Don't ever forget this fact, Cameron, Paul says to remember you were dogs.
Tell me Cameron, does Ephesians have the identical corporate narration as Romans?
Is God giving the green light to the Gentiles now?
I don't think anyone would be talking about a Gentile being elect from eternity.
