I don't want what you personally think is an ironclad, ect argument. I want Scripture. You said what God revealed backed up your assertion that He would not demand the impossible. Yet all I get is your human babblings.
I bet you think "Why doth he yet find fault? For who hath resisted his will?" is an ironclad, irrefutable argument too.
I don't think this is going anywhere.
Evidently not, but all you have to do is pony up. Don't realy on emphatic assertion (which is all your "ironclad" argument boils down too), bring on the revelation.
