What will happen to the whole creation after the curse?
The whole creation will be delivered from the bondage of corruption—the curse—and brought into the glorious liberty of the children of God. It was subjected to vanity not willingly, but in hope, because God promised a Redeemer, the seed of the woman, who is Christ.
Les explains that the creation was made subject to vanity, to the curse, not willingly; it was not creation's fault but Adam's—man's fault—that the curse came in. Yet God subjected that same creation in hope, and immediately after Adam sinned in Genesis 3, God promised a Redeemer, the seed of the woman, who is Christ. Then verse 21 says the creation itself shall also be delivered from the bondage of corruption, which is the curse, into the glorious liberty of the children of God. So all of creation, not just the human race, will be delivered from the curse.
