Let no man deceive himself. If any man among you seem to be wise in this world, let him become a fool, that he may be wise. 19For the wisdom of this world is foolishness with God. For it is written: I will catch the wise in their own craftiness. 20And again: The Lord knoweth the thoughts of the wise, that they are vain. 21Let no man therefore glory in men. 22For all things are yours, whether it be Paul or Apollo or Cephas, or the world, or life, or death, or things present, or things to come. For all are yours. 23And you are Christ's. And Christ is God's.
