Is God ever Silent?

Question:

Is God ever really silent or does it only seem like that to us sometimes because we aren't really listening or just can't hear Him for whatever reason?

I began to wonder this the other day while listening to BarlowGirl sing, "I believe in God even when He is silent."

Then I had a dream last night that was full of dialog with God where through many methods He kept pointing out how we often fall into patterns of using objects & routines as ways of communicating with Him. As an example from my dream--If we find Him behind a curtain then we tend to keep going back to that curtain expecting Him to be there to speak to us every time. We turn the curtain into the object of our attention rather than the living active God who only used the curtain for His purpose in our life once and is now wanting us to be with Him elsewhere.

Back to my question--Is God ever really silent or can we just not hear Him when He speaks because we get so far out of touch?

One could argue that if in no other way--His voice is always present in His created world as described in Romans 1:20 "For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead" and Psalm 19:1 "The heavens declare the glory of God; the skies proclaim the work of his hands." But are these "declarations" from nature remotely equivilant to God actually speaking to us through His Holy Spirit?

What do you think...is God ever silent?
