18 Let no one deceive himself: if any one thinks himself to be wise among you in this world, let him become foolish, that he may be wise.
19 For the wisdom of this world is foolishness with God; for it is written, He who takes the wise in their craftiness.
20 And again, The Lord knows the reasonings of the wise that they are vain.
21 So that let no one boast in men; for all things are yours.
22 Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things coming, all are yours;
23 and ye are Christ's, and Christ is God's.
