According to Paul, creation waits “with eager longing for the revealing of the sons of God” (Rom. 8:19) and “the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God” (8:21). To understand Paul’s point, it is important to remember that this present world was never meant to exist forever. The first Adam was commissioned to finish his task in this world and then to rule in the world-to-come (Heb 2:5). Thus when creation groans (Rom 8:22) for something better, for “the glory” that is coming (8:18), creation is not seeking an improvement of its present existence but the attainment of its original destiny. It longs to give way before the new heaven and new earth spoken of in 2 Peter 3 and Revelation 21.
