Funny how determinism thinks it has a lock on the word "efficacious" and uses it pejoratively by attaching it to human volition.
Only in a deterministic mind is it pejorative. I'm actually OK with it. It does what God designed it to do.
Efficacious Grace Offer <> Efficacious Volitional Receipt (aka faith-obedience) <> Efficacious Grace Salvation.

Romans 10:17-18
So then faith by hearing, and hearing by the word of God. But I say, have they not heard? Yes indeed:
"Their sound has gone out to all the earth, and their words to the ends of the world."
Romans 11:7-10
What then? Israel has not obtained what it seeks; but the elect have obtained it, and the rest were blinded. Just as it is written:
"God has given them a spirit of stupor, eyes that they should not see
and ears that they should not hear,
to this very day."
And David says:
"Let their table become a snare and a trap,
a stumbling block and a recompense to them.
Let their eyes be darkened, so that they do not see,
and bow down their back always."
The Spirit writing through Paul attributes all this hardening by the hand of God Himself nationally to Israel, and every nation is made up of individuals. it cannot be honestly argued that it is merely national, and not also indivual, or the purpose of election could not stand, being decided by men who make up the nation, rather than God Who appoints all things.elsewhere in the same text we have the examples of Pharoah, Jacob and Esau - - all individuals not nations - - saying that God will have mercy on whom He will.
even here He says, the elect obtained, and the rest were blinded. that encompasses individuals within a nation, and both election and having been blinded are passively received by men, not actively accomplished by us.
it is never simple; it's the will of omniscient, omnipotent God in us, turning all things to the good of those who believe.
