David’s 19th psalm is a theological and poetic masterpiece! He begins with the doctrine of general revelation, that the “heavens declare the glory of God,” proclaiming Him as Creator of all. Next, he describes the doctrine of specific revelation, that God has spoken and given us His law and “testimony,” so that we may know His will. Finally, he closes the psalm with the doctrine of redemption, that God is the only One who can help us with our sin problem. We have a “sure testimony” from our God. He has declared His glories from the heavens and revealed His salvation through His written Word and finally, through His Son, the Incarnate Word of God, Jesus.
