'World' in the Bible

first, indeed, I thank my God through Jesus Christ for you all, that your faith is proclaimed in the whole world;

for the invisible things of Him from the creation of the world, by the things made being understood, are plainly seen, both His eternal power and Godhead -- to their being inexcusable;

let it not be! since how shall God judge the world?

And we have known that as many things as the law saith, to those in the law it doth speak, that every mouth may be stopped, and all the world may come under judgment to God;

For not through law is the promise to Abraham, or to his seed, of his being heir of the world, but through the righteousness of faith;

because of this, even as through one man the sin did enter into the world, and through the sin the death; and thus to all men the death did pass through, for that all did sin;

for till law sin was in the world: and sin is not reckoned when there is not law;

but I say, Did they not hear? yes, indeed -- 'to all the earth their voice went forth, and to the ends of the habitable world their sayings.'

and if the fall of them is the riches of a world, and the diminution of them the riches of nations, how much more the fulness of them?

for if the casting away of them is a reconciliation of the world, what the reception -- if not life out of the dead?
