1 Corinthians 1:18-26; 1 Corinthians 2:11-14

18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.

19 For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.

20 Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world?

21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.

22 For the Jews require a sign, and the Greeks seek after wisdom:

23 But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;

24 But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.

25 Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.

26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called:

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.
