The idea of making a joyful noise to the Lord is often associated with singing, but our "noises" don't always have to be audible. When we live a life pleasing to God, we truly begin living loud.
Not long ago, I had an ear infection and a hearing test was part of standard procedures. The doctor tested my hearing by placing me in a completely quiet room, putting headphones on my ears, and telling me to raise my hand whenever I heard a beep. Perfect hearing would mean every single beep was heard, even the most quiet. It occurred to me that we must train ourselves in a similar way to hear the voice of God.
