Our voices united together are the greatest instrument to praise God - in prayer and especially and in song! Yet from ancient times God’s people have used other instruments to accompany our voices in praise and lift our spirits with artistic beauty.
“When the trumpeters and singers were heard as a single voice praising and giving thanks to the LORD, and when they raised the sound of the trumpets, cymbals, and other musical instruments to ‘Praise the LORD, who is so good, whose love endures forever,’ the cloud [the glory of the LORD] filled the house of the LORD.” (2 Chron 5:13)
