“ There are many themes found in the Book of Psalms that are generally not found in modern music. These include the fear of God, the righteousness and justice of God, the sovereignty of God, the judgement of God, the evil of sin, spiritual and physical warfare, the arch enemies of the Christian, the destruction of the wicked, the reality of hell, the blessedness of the church, the vicious attacks upon the church, the commandments of God, the dominion of David’s son, and so on. Without the backdrop of these truths, the themes of love, mercy, faith, and salvation become largely meaningless. ”
