I Corinthians

  1. 2:4  And my speech and my preaching was not with enticing words of man's wisdom, but in demonstration of the Spirit and of power:
  2. 5  That your faith should not stand in the wisdom of men, but in the power of God.
  3. 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.
  4. 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.
