"Worthy music is powerful. It has the power to make us humble, prayerful, and grateful.
"Prophets through all generations have taught the importance of worthy music in our expressions of worship. A few citations from the scriptures may serve to illustrate.
"An Old Testament scripture bids us to 'make a joyful noise unto the Lord, all the earth: make a loud noise, and rejoice, and sing praise' (Psalm 98:4). In the Hebrew language, the meaning of this verse is to literally burst forth into song and to shout for joy. Contrast that spirit of enthusiasm with scenes we may see at church when some sing only passively and without a spirit of joy....
"Music has a sweet power to promote unity and love in the family. Not only is it an important component of family home evenings, but it can also exert a continuing influence for good well beyond times when children are small. For my gift to our family for Christmas 2007, I prepared a compact-disc recording of musical memories. I sat at the piano and recorded a variety of music that I had sung or played to the children through the years. They liked it. Some of the grandchildren told me that the CD was 'cool.'
"Music has power to provide spiritual nourishment. It has healing power. It has the power to facilitate worship, allowing us to contemplate the Atonement and the Restoration of the gospel, with its saving principles and exalting ordinances. It provides power for us to express prayerful thoughts and bear testimony of sacred truths....
"Fill your minds with worthy sights and sounds. Cultivate your precious gift of the Holy Ghost. Protect it as the priceless gift that it is. Carefully listen for its quiet communication. You will be spiritually stronger if you do.
"You know the proverb, 'As [a man] thinketh in his heart, so is he' (Proverbs 23:7). As you control your thoughts, you control your actions. Indeed, worthy music can provide power and protection for the soul."
- Russell M. Nelson, "The Power and Protection of Worthy Music," CES fireside address, May 4, 2008; see Ensign, December 2009, pp. 13-17
