'Some Christians repress their emotions as they sing. They fear feeling everything too strongly and think maturity means holding back. But the problem is emotionalism not emotions. Emotionalism pursues feelings as an end in themselves. It's wanting to feel something with no regard for how that feeling is produced or its ultimate purpose. Emotionalism can also be view heightened emotions as the infallible sign that God is present. In contrast, the emotions that singing is meant to invoke are a response to who God is and what he's done. Vibrant singing enables us to combine truth about God seamlessly with passion for God.'
