Have you ever found yourself humming a favourite childhood hymn, only to realise you could no longer embrace its message? In What a Friend They Had in Jesus, Harry Cook explores how hymns reflect the religious beliefs of their times. He revisits the texts of popular hymns, posing such questions as: How true are they to the biblical texts that seem to have inspired them? What aspects of nineteenth- and twentieth-century piety have persisted into the twenty-first century through the singing of those hymns? And, how does one manage the conflict between the emotional appeal and the theological content of such hymns?
