Which Psalm indicates that the cosmos declares God's glory?

Psalm 19 clearly establishes the concept that the heavens and the cosmos declare God's glory. The opening verses state, "The heavens declare the glory of God; the skies proclaim the work of his hands." This passage emphasizes the idea that nature itself serves as a testimony of God's creative power and majesty. The psalm goes on to illustrate how creation communicates knowledge and wisdom, highlighting the innate connection between the divine and the natural world.

In contrast, the other psalms address different themes. Psalm 8 reflects on humanity's role within creation and God's care for mankind, while Psalm 23 focuses on God as a shepherd who guides and provides for His people. Psalm 121 expresses trust in God's protection. Each of these psalms has its unique message, but only Psalm 19 explicitly describes the universe as a communicator of God's glory.
