κόσμος
kósmos · noun · “world”
Kosmos means world — sometimes the universe God made, sometimes humanity, and often the present age in its rebellion against God. Context tells which.
Kosmos can mean the created universe (“the world that he made”), the inhabited earth and its people (“God so loved the kosmos”), or the present world-system organized in opposition to God (“do not love the world”).
These uses must be read in context. The same word can speak of what God loves and gave his Son for, and of what the believer is not to be conformed to. Both are true: God loves people in the world, and warns them away from its rebellion.
Definition: orderly arrangement, i.e. decoration; by implication, the world (in a wide or narrow sense, including its inhabitants, literally or figuratively (morally))
KJV usage: adorning, world
