'Of the World' in the Bible

For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; that they may be without excuse:

For not through the law was the promise to Abraham or to his seed that he should be heir of the world, but through the righteousness of faith.

But I say, Did they not hear? Yea, verily, Their sound went out into all the earth, And their words unto the ends of the world.

Now if their fall, is the riches of the world, and their loss the riches of the Gentiles; how much more their fulness?

For if the casting away of them is the reconciling of the world, what'shall the receiving of them be , but life from the dead?
