The Grace of Ilúvatar?

True, but the mind of Eru, who I think this question is referring to, sees the true intent behind a repentance. Meaning He really knows whether you're sorry or not and there is no way to fool Him.

Oh you cad. You don't give it to somebody that is so naughty that they have refused every opportunity to repent their sinning ways.

I think he's got a point here. If a person refuses the grace that is being offered, can he receive it? I'd say no. The Noldor are a prime example. They forsook the 'grace' of living in Aman and left. At that point, the offer of 'grace' was withdrawn from them so that they could not come back, like Estelyn mentioned.
