(Isa. 12:5)
The admonition to “sing unto the Lord” is not one that is reserved for the redeemed remnant of the future. Sacred music invites the Spirit of the Lord into our midst and is a wonderful way in which to worship Deity. Modern revelation reminds us that the Lord’s “soul delighteth in the song of the heart; yea, the song of the righteous is a prayer unto [Him]” (D&C 25:12).
(Hoyt W. Brewster, Jr., Isaiah Plain and Simple [Salt Lake City: Deseret Book Co., 1995], 122.)
