So why would a being like God elect to make Salvation a human choice thing?

He's going to save all of humanity, you tell me. I'm a part of humanity. I refuse point-blank to be saved. Where does that leave me? Still singing out of tune around the Throne through gritted teeth, completely unwilling but compelled by force?

If I've misunderstood you and I can successfully refuse salvation then He's not going to save all of humanity and it turns out that, despite what you started with, Salvation is a human choice thing after all. I'd rather hoped it was.
