What does the church most need today? In answering this important but rather general question, Psalm 81 is uniquely important and helpful. This psalm obviously contains beautiful promises and clear directions to help the people of God. But careful study of this psalm will deepen our appreciation of it, increase its value for us, and show us how distinctive it is for helping the church.
As we study psalms, we soon learn that the central verse of a psalm is often significant as a key to its interpretation. The central line of Psalm 81 is the heart of that psalm, as the plaintive cry of God is heard: “O Israel, if you would but listen to me!” (v. 8b). The center of Psalm 81—indeed the whole psalm—is a reflection on the Shema.
