When God is Silent

I have been preaching in our new services for several weeks now, and it has been going really well.  Though I have been posting all of the videos on my vimeo account, I have decided to not post ever week's sermon here; however, I received so many comments about this one that I decided to place it here.  At the heart of this sermon is a desire to answer questions around the experience of the Silence of God.  So... when God is silent, where is he?  Why is he silent?  What am I supposed to do?
