He gives some grace, whether they want it or not.
So He'll fudge the rules for some, and not others? I can't help but find that--not arbitrary, for if anything has a reason, God does--but simply cruel.
If God were cruel, He could simply do justice and damn everyone without exception.
The fact that even one person is saved is a wonder of mercy.
The fact that one is doomed is a travesty of cruelty, if they have no chance to avoid it.
How is making a creature you know is faulty and then allowing it to propogate so that you can make them all suffer eternally "just?"
