These or similar worlds are often said by Christians when talking about Creation. If the world is going to be destroyed, we don't really need to worry about it.
Western Christianity has been deeply affected by the idea that there are two "things": the spiritual and the material. The material is viewed as at best a temporary good, but more often as something not good. It is the spiritual that is the real good.
There is no question that there is something wrong in Creation. The Fall "broke" Creation. We see death and decay all around.
But the God who created, and placed his stamp of approval on Creation in the Incarnation is not going to throw Creation away. His plan is to remake it!
18 I consider that the sufferings of this present time are not worth comparing with the glory about to be revealed to us. 19For the creation waits with eager longing for the revealing of the children of God; 20for the creation was subjected to futility, not of its own will but by the will of the one who subjected it, in hope 21that the creation itself will be set free from its bondage to decay and will obtain the freedom of the glory of the children of God. 22We know that the whole creation has been groaning in labour pains until now; 23and not only the creation, but we ourselves, who have the first fruits of the Spirit, groan inwardly while we wait for adoption, the redemption of our bodies. (Roman 8 18-23)
The whole gospel of John is a story of New Creation (It begins "In the beginning and ends with a "man" in a garden!). Rev 21 portraits a new Jerusalem.
God's plan of redemption encompasses the whole Cosmos!
