Observation: Paul is continuing about the fact the church in Corinth keeps declaring 'who' they believe - which apostle each of them was either converted by or likes best - as an example that they are still young in their faith. As he is about to conclude, he echoes back to his prior comment about wisdom. He has already been critical of how some desire wisdom, or logic, as evidence of faith, and that God's ways are to confound such logic through what appears to be foolishness but is actually even greater wisdom. Now again, Paul tells Christians to avoid the common wisdom of people, and become "fools" who do not comply with worldly wisdom.
Interestingly, when Paul earlier talked about wisdom, he was talking logic ... philosophical rational and debate that would intellectually present God and Jesus and faith. Now, Paul is presenting this conversation in the context of worldly alignment to people and their teachings/actions. This type of wisdom, therefore, is not about philosophical understanding, it is about qualitative, hierarchical concepts. This is addressing the idea that, when it comes to topics ranging from educational sources to political power, the world creates hierarchies, classifying and considering certain sources or factions as superior. The church at Corinth is doing this with their apostles, not only declaring whom they like the best, but also (probably) which of them had superior theology (maybe Paul) or pedigree (certainly Peter) or speaking ability (likely Apollos).
This is a very human structuring of the world, and thus very much about worldly wisdom. In all sorts of matters, humans either a) follow and like one person over another, and then promote that person as superior, or b) decide which person or group is superior, and then follow their teach or methods or advice. Paul is clear ... that's not what to do when it comes to obedience to the Lord and faith in Jesus. These classifications, which the world almost mandates and declares to represent a wise method of analysis, are worthless. Worse, they are a trap, which will catch humans in their craftiness by turning faith in Jesus into an analysis of that which is not Jesus.
Application: I had not thought about this form of worldly wisdom before. I know I absolutely hate conversations about things like ... oh, just to pick a random topic ;-) ... the "right" political party, but now I see that such discussions are part of the worldly condition of attempting to define and then align to some hierarchical qualitative analysis. That is absolutely not the way any conversation of faith should be structured and practiced.
I don't think this is the same as - for example - listening to two pastors and deciding you like one best. God may have a certain message he wants you to hear, and speaks into one of those pastors on such topics while giving a different emphasis to the other. However, my wife and I once visited a church that had two pastors; One preached at one service, the other at the other, and people we talked to said things like 'well I'm part of the Pastor X church, others follow Pastor Y'. THAT seemed very unhealthy. That wasn't about having a spirit-driven preference for one style or message, it was about dividing the church based on a classification of two men.
We have so many divisions in the world based on humans classifying subjects along a superior-inferior continuum, and then deciding which subject they will adhere to. The continuums are often identified based on who is leading the conversations on the subjects, and the continuums are always personal and thus not really meaningful as a way of evaluating what is 'good'.
And that, of course, is the point. There is no wise way to classify good in the world except one, which is by the word and will of the Lord. There is no person to align to except one, Jesus. There is no wise power to help us discern except one, which is the Holy Spirit.
I want to foolishly disregard the classifications of this world.
Prayer: Lord, over and over again you give me of yourself even though I don't deserve it. I am in need of wisdom now, and therefore I will not seek wisdom. May I only look to you for guidance and direction about what to do in my life, and be foolish in the eyes of the world. Amen.
