It seemed as though God was killing the psalmist prematurely. He prayed for a continuation of his life. This request led him to reflect further on the duration of God's existence. To picture God's ceaseless continuance he referred to the creation (Gen. 1) and then the consummation of the present heavens and earth (Rev. 21:1; cf. 2 Pet. 3:10). His point was that God will outlast His creation. Really God is eternal having no beginning or ending (v. 27). Therefore He will preserve the children of His servants who were then in danger of dying or had already died.
The writer to the Hebrews applied verses 25-27 to Jesus Christ (Heb. 1:10-12; 13:8). He is the Person of the Trinity who created and sustains all things. These verses are some of the clearest and most majestic revelations of God's eternal nature in Scripture. This revelation gave the psalmist hope in his personal distress. In the same way a knowledge of God's changeless ceaseless character can be a great comfort to all of God's people when we suffer. It helps to view personal suffering in the context of eternity.
