Timid singers or shrinking wall flowers need not apply to sing in Global/Church of the Eternal God COG services. If you sing too softly you are sinning against their god. Loud singing is a requirement!
In services, most of us do not have many opportunities to audibly participate, except for saying “Amen” to the opening and closing prayers, after having listened carefully and attentively to every word of the prayers, and for singing joyfully during the song service. We cannot overemphasize the importance of participation in the song service with all of our heart, concentrating on each word which we are singing, and agreeing with it completely, knowing that we are not doing so to impress others, but because we are worshipping God when we sing out loud. There have been rare occasions when a brother or sister was told not to sing so loud, but this would be highly inappropriate “advice.” In fact, the song leader should encourage the congregation in words and by his own example to sing out loud and with enthusiasm.
Notice what we read about singing songs and hymns to God:
“Make a joyful noise unto God, all ye lands: Sing forth the honour of his name: make his praise glorious” (Psalm 66:1-2, AV).
This is the law as laid down by Norbert Link
