Imagine an epistle that starts with "Blessed be God the Father of our Lord Jesus Christ whom we have chosen of our own free will"
It is almost laughable.
Jesus said "You have not chosen Me but I have chosen you" We are God's elect, or His chosen people.
In order to choose we would need to have free will but Paul says we were slaves of sin, slaves of Satan, in bondage to the elementary spirits of the universe. None of that spells free will.
They have turned everyone to his own way and esteemed Him not. What then?
The answer is God must subdue that "free will" which has led us into rebellion. He subdues us with love, with kindness [sometimes love and kindness of the rougher sort] He lassos us like the cowboy lassos the wild bull or horse and brings us down to the dust. He hogties us so that we can't move every which way.
The bible says "He wills IN US to do of His good pleasure" it may seem like we are choosing but really it is Him IN US who is choosing.
There was a day when Smith Wigglesworth [I wonder if you have heard of him] was preaching in the north of England and there was a young man at the back calling out and heckling disrupting the meeting, He chose the wrong preacher to do that for Wigglesworth was a bluff Yorkshire man and nobody with any sense will argue with a bluff Yorkshire man.
Wigglesworth leapt off the platform and made his way to the back, the young feller took fright and ran for the door but Wigglesworth made a flying rugby tackle and brought him crashing to the floor and pinned him to the floor. The young man screamed "let me go, let me go"
Wigglesworth said "repent and believe and I'll let you go" ... "I repent, I believe, I repent, I repent" so Wigglesworth let him go.
Of course the young feller didn't get saved like that but actually after a couple of weeks he did repent and get saved.
All that doesn't fit what we discussing but I thought I'd throw it in.
