Thats gross error, Grace which has to do with God in Salvation makes alive, commences a new creation. It has nothing to do with the creatures will, but only with the Creators will. Grace finds man dead in sin, then according to Gods will, quickens or makes the dead alive Eph 2:5
Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved)
The elect are saved by grace because they were made alive from the Spiritual Dead.
Prevenient grace as you describe doesnt make alive, so its tripe, worthless.
So please stop Identifying with effectual grace,, because you dont really believe it.
