18 eLet no one deceive himself. fIf anyone among you thinks that he is wise in this age, let him become a fool that he may become wise. 19 For gthe wisdom of this world is folly with God. For it is written, h“He catches the wise in their craftiness,” 20 and again, i“The Lord knows the thoughts of the wise, that they are futile.” 21 So jlet no one boast in men. For kall 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 lyou are Christ’s, and mChrist is God’s.
