Music is more than just “mood accompaniment” for preaching. Music is an important way that the people of God conduct spiritual warfare and the way we teach one another in the gospel (Eph. 5:15-20).
In the old covenant, God gifted, by his Spirit, the musicians of the people of Israel, with a high responsibility for leadership. In the new covenant, the gifts of the Body come from a triumphant Christ, and are for the upbuilding of the rest of the church (Eph. 4:7).
