God is always speaking...

Let me hear what God the Lord will speak,

 for he will speak peace to his people, to his saints;

   but let them not turn back to folly.

-Psalm 85:8

God is always speaking; He is never still. Just as in prayer it is not we who momentarily catch His attention but He ours, so when we fail to hear His voice it is not because He is not speaking so much as that we are not listening.  

-Charles H. Brent
