'Of This World' in the Bible

Where is the wise man (philosopher)? Where is the scribe (scholar)? Where is the debater (logician, orator) of this age? Has God not exposed the foolishness of this world’s wisdom?

Yet we do speak wisdom among those spiritually mature [believers who have teachable hearts and a greater understanding]; but [it is a higher] wisdom not [the wisdom] of this present age nor of the rulers and leaders of this age, who are passing away;

not meaning the immoral people of this world, or the greedy ones and swindlers, or idolaters, for then you would have to get out of the world and human society altogether!

and those who use the world [taking advantage of its opportunities], as though they did not make full use of it. For the outward form of this world [its present social and material nature] is passing away.
