This past weekend I was helped by Bob Kauflin's talk at the Desiring God's Fall Conference. He made an important distinction between emotions and emotionalism. He also made the point that the gospel is what unites us in corporate worship, not music (or preaching style etc). You can check out the talk at http://www.desiringgod.org/ResourceLibrary/MediaPlayer/3260/Video/ May God continue to give us grace to think biblically about the arts in the church.
