The melody of song poured forth from many hearts in clear, the distinct utterance is one of God's instrumentalities in the work of saving souls - Prayer p. 211.5, Ellen G. White.

I will sing to the LORD as long as I live;
I will sing praise to my God while I have my being.
May my meditation be sweet to Him;
I will be glad in the LORD.
May sinners be consumed from the earth, and the wicked be no more.
Bless the LORD, O my soul!
Praise the LORD! (Psalms 104:33-35, NKJV)
