creation: God's act of creating, and the created world that act brings into being.
This one word travels the whole distance from God's act of making the world to the world that results from it, and English has no single word that covers the same span.
At one end it names the event itself, the founding of the world, as in the phrase "from the beginning of creation." At the other end it names the finished product, everything God has made, which Paul pictures groaning and waiting to be set free. In between it can narrow to a single created thing, a creature, and it can widen again to the whole renewed order that God begins in Christ, the "new creation."
The related verb κτίζω is the act of creating, and κτίσμα is an individual created thing; this noun can mean either the act or its result, which is why the same word points at both the making and the made. It overlaps with κόσμος, the ordered world, but the emphasis differs: this word stresses that the world is something made, while κόσμος stresses the world as an arranged system.
