As soon as we had done this, it really opened up a new avenue of studying the OT to me. I was suddenly able to see the same gospel themes exposed in a great many places, and among them the Psalms.
My initial forays into the Psalms were borne, I think, of my own introspection and the comfort they brought to a naïve eighth-grader who felt like he was picked on more than his due in school. My second shot into the Psalms was more mature, guided by the realization that many of them provide glimpses into the nature of Jesus Christ and the Godhead. Many of the Psalms still remained a mystery to me, at least in the sense that I was looking for something in the white spaces, the background of the story.
(As an aside, this is a sometimes destructive tendency for me and has certainly put me into some rather poor doctrinal positions in the past. Ockham's Razor is certainly not the best thing to happen to Christianity, but it's a rather useful tool when dealing with difficult passages.)
The key was the content of the gospel, elements identified by their presence in obvious gospel passages (Isaiah 40-45, 53, and many others). They consist mainly of God's attributes:
- righteousness, judgment (94.1,15; 96.10,13; 97.2,6,8; 98.2,9; 99.4)
- power, might (93.4; 95.4,6; 96.3-5; 98.1)
- reign (93.1; 95.3; 96.10; 97.1; 99.1)
- mercy, lovingkindness (98.3)
- faithfulness
- salvation (96.2; 98.2,3)
- truth
Man's response to these attributes is uniformly supposed to be praise (a fact I find interesting, considering all of the emphasis we place on belief). See (95.1,2; 96.1-3; 97.8,12; 98.1,4-9; 99.3,5,9).
Not surprisingly, each of these occurs in great quanity in the Psalms. I've provided some references from our latest readings in the bulleted list.
If we chart these themes throughout Scripture, we'll find them in some measure in the almost spontaneous doxologies in the Pauline epistles and other letters, and in equal measure in the songs in Revelation (cp Re 14.6—"eternal gospel"). And they figure quite prominently in Mary and Elizabeth's songs in Luke 1, and in Simeon and Zarachrias' proclamations, also.
While the Psalms sometimes get a bit repetitive, it has been one of my constant delights to find them such a well of incredible depth. We so often shrink the gospel into a formula that it's difficult to keep in mind what it's really about.
