'Age' 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;

None of the rulers of this age recognized and understood this wisdom; for if they had, they would not have crucified the Lord of glory;

Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool [discarding his worldly pretensions and acknowledging his lack of wisdom], so that he may become [truly] wise.
