'Of This World' in the Bible

Where is a wise man? Where is a scholar? Where is a researcher of this age? Did not God make foolish the wisdom of this world?

For the wisdom of this world is foolishness before God. For it is written, He who catches the wise in their craftiness,

and not at all with the fornicators of this world, or with greedy men, or with predators, or with idolaters, since then ye would need to go out of the world.

and those who use this world, as not making full use, for the form of this world passes away.
