'World's' in the Bible

And for those who make use of the world, not to be using it fully; for this world's way of life will quickly come to an end.

But if a man has this world's goods, and sees that his brother is in need, and keeps his heart shut against his brother, how is it possible for the love of God to be in him?

They are of the world, so their talk is the world's talk, and the world gives ear to them.
