What do you call 'free will?' What is it? How does it work?...

Fair enough. That's all that can be expected.
Then why:

What do you call 'free will?' What is it? How does it work? Instead of just declaring 'we have free will,' you need to give a description and an argumentto support your declaration.

You must know that debate on the nature or reality of free will, whatever that is supposed to be, spans centuries, so a declaration isn't going to settlethe issue. You need an argument supported by evidence.

Free will is suggested to be the determination to love God and neighbour with the entire being although every inclination of the being is to be evil.
Which is to not love God and neighbour with entire being.
The evidence is fractured societies and an ugly history of the world by free will towards evil inclinations.
