'Of This World' in the Bible

For the wisdom of this world is foolishness with God, for it is written, "The one who catches the wise in their craftiness,"

By no means [did I mean] the sexually immoral people of this world or the greedy people and swindlers or idolaters, since then you would have to depart out of the world.

and those who make use of the world as [if they] do not make full use of [it]. For the present form of this world is passing away.
