Psalm 103 is a Davidic Psalm rich with Messianic hope and assurance. This song introduces a set of 4 Psalms (103-106) which share themes from creation through the era of exile, as they illustrate the relationship of the Lord to His people. Psalm 103 and 104 share opening and closing refrains. Both Psalms instruct the singer himself to direct his admiration, affections, and worship to Yahweh... “Bless the LORD, oh my soul”. Ps 103 proceeds with a catalogue of reasons for praise, documenting with poetic symmetry, the benefits of the Lord extended to His children (2,13). The praiseworthy glories of God multiply in the memory of David as he sings, overwhelming him with the immeasurable worth of his Lord and moving him to call on all the hosts of creation: heaven, earth, and works to join him in jubilant adoration! The crescendo of worship builds through the Psalm multiplying reasons for worship and voices to join him. Ps 103 parallels the great arc of history in its structure. The mighty works of God are multiplied through the ages as the gospel sickle reaps its international harvest unto the culmination of redemptive history pictured in the glorious crescendo of worship in Revelation (7, 14) where men and angels join in forever praise of the Lamb slain for the redeemed. In addition, Ps 103 is structured with a kind of mirror symmetry which directs the focus of our attention to its epicenter in verses 11 & 12. Here, the great theme of this section of the Psalter is encapsulated as David pairs the greatness of the Lord and His work with its covenantal application to the redeemed considering their desperate situation. How could we forget such high, holy, and essential truths to which we owe our eternal destiny? How tragic to so often forget and neglect so great a salvation! Therefore David declares war on forgetfulness, commanding his soul to bless the Lord. He does so by recounting the mercies and glories of God extended to the elect... bidding us: “Do not forget the following!”
