From Howard Stevenson in "Mastering Worship":
"If a good sermon needs time to develop and drive home a point, so does authentic worship. Worship needs at least fifteen to twenty minutes to build. In our church, we normally devote thirty minutes to worship- congregational singing, special music, and Scripture readings.
In order to devote that kind of time, we strive to eliminate as many nonessentials as possible. We want to give maximum time to worship and congregational singing. We know sermonettes produce Christianettes, and we don't want to find out what shortened worship produces."
