John D. Witvliet reminds us that every time we sing praise to the triune God, we are asserting our opposition to anything that would attempt to stand in God’s place. Every hymn of praise is a little anti-idolatry campaign, as Walter Brueggemann explains: “The affirmation of Yahweh always contains a polemic against someone else. . . It may be that the [exiles] will sing such innocuous-sounding phrases as ‘Glory to God in the highest,’ or ‘Praise God from whom all blessings flow.’ Even those familiar phrases are polemical, however, and stake out new territory for the God now about to be aroused to new caring”
