What does Psalm 8:9 mean?

Psalm 8 ends as it begins. David addresses the LORD, our Lord, and exclaims, "How majestic is your name in all the earth!" Like us, David's view was that of nature under a curse imposed on it because sin had entered the world. God told Adam: "Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, 'You shall not eat of it,' cursed is the ground because of you" (Genesis 3:17).

We can only wonder how beautiful nature was before the curse. Someday, when Jesus returns to rule the earth, He will roll back the curse, and once again it will resemble God's creation before sin entered the world. Romans 8:19–21 says, "For the creation waits with eager longing for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope that the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God." Isaiah describes the earth under Jesus' kingdom rule as so stunning that the desert will blossom abundantly (Isaiah 35:1–2).
