'Of This World' in the Bible

where is the wise? where the scribe? where a disputer of this age? did not God make foolish the wisdom of this world?

for the wisdom of this world is foolishness with God, for it hath been written, 'Who is taking the wise in their craftiness;'

and not certainly with the whoremongers of this world, or with the covetous, or extortioners, or idolaters, seeing ye ought then to go forth out of the world --

and those using this world, as not using it up; for passing away is the fashion of this world.
