While considering music in Amos, we should note Amos 6.
Woe to those who are at ease in Zion…. Woe to those who lie on beds of ivory and stretch themselves out on their couches, and eat lambs from the flock and calves from the midst of the stall, who sing idle songs to the sound of the harp and like David invent for themselves instruments of music, who drink wine in bowls and anoint themselves with the finest oils, but are not grieved over the ruin of Joseph! (Amos 6:1, 4-6)
Fun and feasting are not wrong. God directs His warning (“woe”) at merrymaking that shows carelessness in the face of rampant sin and impending disaster. In the setting of Amos 6, the music is part of human pleasure, like wine and fine food. All who enjoy strumming guitars and experimenting with new arrangements can understand that pleasure.
That introduces another mystery. Music certainly pleases our human ears, but what about the ears of God? Does He have ears like ours? Do His eardrums vibrate to musical tones, sending signals that the mind translates as pleasure? This same question arises from other Old Testament offerings. Does God have nostrils that enjoy the smell of burning incense? Does He salivate at the smell of meat roasting on the altar? Does God have an appetite for grain? As we shall see, the Old Testament itself raises that kind of inquiry. As the mystery deepens, we will revisit these questions.
