Music is so important that God's children have used it for many purposes throughout history! In fact, they not only played music and sang songs, but they recorded them as well!--Not with the advanced methods we use today, but in whatever ways they could, and you can read in the Bible the recorded words of some of the earliest Christian songs.
Moses was a singer and writer. David wrote a whole book of songs, the Book of Psalms! Jeremiah wrote a song now known as Lamentations. Hannah, the mother of Samuel, wrote songs (1Sam.2), and Deborah and Barak sang a duet before the Children of Israel! (Judges 5) The Lord even used musical instruments to save His children from their enemies, like the trumpets which caused the walls of Jericho to fall (Joshua 6), and the Midianites to flee from Gideon's meager army of 300 men. (Judges 7) You can read all through the Bible how God's children were constantly singing and making a "joyful noise unto the Lord". (Psa.100:1) Even Jesus and His disciples sang songs (Mat.26:30), and Paul exhorts that we should all sing psalms and spiritual songs. (Col.3:16) John even heard singing in Heaven--the song of Moses! (Rev.15:2,3)
So "come, let us sing unto the Lord!" (Psa.95:1)
