A thought about worship technique. Too many times I've heard a reader or preacher speak too quickly, too indistinctly or both to be easily understood. A large room and poor (or missing) amplification and you can give it up.
If this is your problem to overcome, I'd like to commend listening to the Voice of America's Learning English (formerly Special English) broadcasts. They are spoken slowly, clearly and in a simplified vocabulary. It's really quite easy to listen to, and this particularly notable when an interview subject mumbles, speeds or makes verbal curlicue. The pacing isn't always right for worship, but the price is.
