'Worship' interview with Don Carson

Here is an excerpt from that interview:
"...This is why I don't like things that go on and on, repeating the same thing again and again. They are like mantras. They worry me. Not that there shouldn't be any repetition-some of the psalms are repetitious-but when it becomes a way of building people up to an emotional high, it's a form of manipulation that is not godly.
But on the other hand, I don't want to be afraid of the articulation of truth, both in a sermon and through song, that breaks people down in tears. I've been in some wonderful Christian meetings that have been powerful emotionally, so long as we aren't trying to achieve it by manipulation-either by the preacher telling a weepy story for effect, or for mantra-like chants that get people all worked up. If the truth of the gospel is being rightly expressed through word and song, then we should not be afraid of emotion.
My mother died of Alzheimer's disease, over nine years. Nine or ten months before she died, you'd get a small flicker from the eyes or squeeze of the hand if you held up pictures of her grandchildren. Six months before she died, if you sang an old hymn like 'Blessed assurance, Jesus is mine', you'd get a squeeze. Or a quote from the King James Version that she'd been brought up on. That was about the last thing that produced any response in her. The most deeply embedded memories in that decaying brain were those old hymns and memorised Scripture. There is something worrying to me about a generation that sings choruses that won't last more than five years. There's not much memorization of Scripture, and there's not much memorization of doctrinally profound hymns. I want to see that reborn. Nobody's going to die remembering 'He's a great big wonderful God'."
