God the Stutterer, God the Reluctant

I've always wondered why we repeatedly pray to God to be willing to grant us Shabbat, etc.  What does it mean to be willing, or to be capable of exercising one's will?  Free will and the exercise of will always comes up when trying to understand Pharoah's will and heart-hardening in Shemot, and so I use sources there to answer the question.  The conclusion touches on how our relationship to God is different from our relationship to Torah.  God, like Moshe, may not always be speaking or willing, but the Torah always is.
