^18 (A)Let no one deceive himself. ^(B)If anyone among you thinks that he is wise in this age, let him become a fool that he may become wise. ¹⁹ For ^(C)the wisdom of this world is folly with God. For it is written, ^(D)“He catches the wise in their craftiness,” ²⁰ and again, ^(E)“The Lord knows the thoughts of the wise, that they are futile.” ²¹ So ^(F)let no one boast in men. For ^(G)all things are yours, ²² whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all are yours, ²³ and ^(H)you are Christ's, and ^(I)Christ is God's.
