1 And I, brethren, when I came to you, came not
      with excellency of speech or of wisdom, declaring
      unto you the testimony of God.
       2 For I determined not to know any thing among
      you, save Jesus Christ, and him crucified.
       3 And I was with you in weakness, and in fear,
      and in much trembling.
       4 And my speech and my preaching was not with
      enticing words of man's wisdom, but in
      demonstration of the Spirit and of power:
       5 That your faith should not stand in the wisdom
      of men, but in the power of God.
       6 Howbeit we speak wisdom among them that are
      perfect: yet not the wisdom of this world, nor of
      the princes of this world, that come to nought:
       7 But we speak the wisdom of God in a mystery,
      even the hidden wisdom, which God ordained before
      the world unto our glory:
       8 Which none of the princes of this world knew:
      for had they known it, they would not have
      crucified the Lord of glory.
       9 But as it is written, Eye hath not seen, nor
      ear heard, neither have entered into the heart of
      man, the things which God hath prepared for them
      that love him.
      10 But God hath revealed them unto us by his
      Spirit: for the Spirit searcheth all things, yea,
      the deep things of God.
      11 For what man knoweth the things of a man, save
      the spirit of man which is in him? even so the
      things of God knoweth no man, but the Spirit of
      God.
      12 Now we have received, not the spirit of the
      world, but the spirit which is of God; that we
      might know the things that are freely given to us
      of God.
      13 Which things also we speak, not in the words
      which man's wisdom teacheth, but which the Holy
      Ghost teacheth; comparing spiritual things with
      spiritual.
      14 But the natural man receiveth not the things
      of the Spirit of God: for they are foolishness
      unto him: neither can he know them, because they
      are spiritually discerned.
      15 But he that is spiritual judgeth all things,
      yet he himself is judged of no man.
      16 For who hath known the mind of the Lord, that
      he may instruct him? But we have the mind of
      Christ.
