19For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness. 20And again, The Lord knoweth the thoughts of the wise, that they are vain. 21Therefore let no man glory in men. For all things are yours; 22Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours;23And ye are Christ's; and Christ is God's.
