18 Do not deceive yourselves. If you think that you are wise in this age, you should become fools so that you may become wise. ¹⁹For the wisdom of this world is foolishness with God. For it is written,
‘He catches the wise in their craftiness’,
²⁰and again,
‘The Lord knows the thoughts of the wise,
   that they are futile.’
²¹So let no one boast about human leaders. For all things are yours, ²²whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all belong to you, ²³and you belong to Christ, and Christ belongs to God.
