'Of This World' in the Bible

But we speak wisdom among the perfect; yet a wisdom not of this world, nor of the rulers of this world, who are coming to nought;

For the wisdom of this world is foolishness with God; for it has been written, "He Who taketh the wise in their craftiness."

not at all meaning, with the fornicators of this world, or with the covetous and extortioners, or idolaters; since ye ought, in that event, to go out of the world;

and those who use the world, as not using it to the full; for the fashion of this world is passing away.
