Can God save a closed heart?

[sola fide]

I think I'm dragging up an old conversation here, but I have a question. I may have missed this somewhere else in this thread, but here it is.
What is the scripture reference about God not violating the will of man?
By no means do I believe that He does violate man's will, but I'd like to know the scripture that backs that statement up.

Soli Deo gloria!

I'm not sure if there is an accual scripture that specifically says it, but the concept is demonstrated though out the bible. 1 cor. 13:5 says that love doesn't seek its own, or pursue its own will at the expence of another's. The amplified says that it does not insist on its rights or its own way.
