I like the Bishop Street’s description of this part of their worship:
Singing: This just might take your breath away. We’re pretty enthusiastic about the privilege of worship in song. If you feel comfortable, please join right in; there are no professionals here, just everybody pouring out hearts to God together. (And don’t worry if you think your voice isn’t quite up to par. If your heart is, that’s what matters.) You might hear quite a variety of song tempos and lyrics and styles, but they all have the intent of praising Father, Son, and Holy Spirit, and also of teaching and encouraging each other. This is what we read about, and are commanded to do, in Ephesians 5:19 and Colossians 3:16. (By the way, many people are surprised by the absence of musical instruments. That’s simply because the New Testament only speaks of singing and making melody in the heart, so that’s the pattern we try to follow.)
The whole page is nicely done.
