The Triumphalism of "Joy, Joy, Joy . . ."

Do Our Worship Songs Have Room for Lament?

Perhaps . . . [the Western church] has drunk so deeply at the well of modern Western materialism that it simply does not know what to do with such cries (of lament) and regards them as little short of embarrassing.

Carl Trueman, “What Can Miserable Christians Sing?” in The Wages of Spin (pp. 159-160):

A diet of unremittingly jolly choruses and hymns inevitably creates an unrealistic horizon of expectation which sees the normative Christian life as one long triumphalist street party—a theologically incorrect and a pastorally disastrous scenario in a world of broken individuals.

Has an unconscious belief that Christianity is—or at least should be—all about health, wealth, and happiness corrupted the content of our worship?

. . . In the psalms, God has given the church a language which allows it to express even the deepest agonies of the human soul in the context of worship.

Does our contemporary language of worship reflect the horizon of the expectation regarding the believer’s experience which the psalter proposes as normative?  If not, why not?

Is it because the comfortable values of Western middle-class consumerism have silently infiltrated the church and made us consider such cries irrelevant, embarrassing, and signs of abject failure?
