For centuries the book of Psalms has been read as a random collection of poems with no intentional arrangement. But is this a correct understanding? O. Palmer Robertson equips us to see a clear redemptive-historical progression that develops across the five books of Psalms. With the aid of charts in full color, he demonstrates how an intentional structure is indicated by elements such as the placement of acrostic psalms, strategic couplings of Messianic psalms with Torah psalms, and the grouping of psalms by topics. If you love the psalms, Robertson will give you a better grasp of the whole Psalter and a deeper appreciation of each individual poem.
