18. Let no person deceive himself. If anyone among you supposes that he is wise in this age, let him become a fool [let him discard his worldly discernment and recognize himself as dull, stupid, and foolish, without true learning and scholarship], that he may become [really] wise. [Isa. 5:21.]
19. For this world's wisdom is foolishness (absurdity and stupidity) with God, for it is written, He lays hold of the wise in their [own] craftiness; [Job 5:13.]
20. And again, The Lord knows the thoughts and reasonings of the [humanly] wise and recognizes how futile they are. [Ps. 94:11.]
21. So let no one exult proudly concerning men [boasting of having this or that man as a leader], for all things are yours,
22. Whether Paul or Apollos or Cephas (Peter), or the universe or life or death, or the immediate and threatening present or the [subsequent and uncertain] future–all are yours,
23. And you are Christ's, and Christ is God's.
