'Of the World' in the Bible

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

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

Now, if their trespass 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 will the receiving of them be, but life from the dead?
