While much modern scholarship has tended to "despiritualize" the Psalms, this collaboration by three evangelical scholars carefully attends to the two voices of the Holy Spirit -- heard infallibly in Scripture and edifyingly in the church's response."The Psalms as Christian Lament," a sequel to "The Psalms as Christian Worship," uniquely blends verse-by-verse commentary with a history of Psalms interpretation in the church to examine ten lament psalms, including the seven traditional penitential psalms. Though C. S. Lewis called the "imprecatory" psalms "contemptible," Waltke, Houston, and Moore show that they too are profitable for sound doctrine and so for spiritual health.
