How Does the Creation Groan?
Many commentators appeal to in this passage to justify the coming of a second literal earth. They suggest that the "creation groaning" refers to the physical creation and it will be renewed after the second coming of Christ. This is not correct. The Bible teaches that this creation will be burned up (2 Peter 3:7-12). So the creation as a whole is not going to be redeemed. Only the individuals who become sons of God will be redeemed, both body and spirit.
