This video is worth 20 minutes of your time.  This man, Benjamin Zander, does a brilliant job of explaining some of the appeal of music (esp. classical music) with passion and clarity.  He reminds me of a well-known quote from DA Carson:

 I have been teaching for several decades now and I have learned something about what our students learn… they don’t learn everything Don Carson teaches them, they tend to learn what I am excited about.   So if I get into the place where I assume the gospel, but I’m really excited about all the social justice issues, then without ever once denying anything essential to the gospel, my students will then be fastened on the social justice issues and the gospel will become less and less important to them, now for me it may be very important to me but I’m assuming it in my teaching, but that means that in another generation or two at the most, the gospel is lost, absolutely lost.

Most people in the social justice movement from the 1880’s to the 1930s thereabouts didn’t begin by denying the gospel, they began by assuming it but no longer being excited by it, while they moved on to other things and the next generation lost the gospel.

People learn not merely by listening to us, but also by watching.  What are we passionate about?  Most importantly, am I passionate about the gospel, and can those around me discern it?
