1 Corinthians 1

Alma taught his son Helaman -

"Now ye may suppose that this is foolishness in me; but behold I say unto you, that by small and simple things are great things brought to pass; and small means in many instances doth confound the wise.
7 And the Lord God doth work by means to bring about his great and eternal purposes; and by very small means the Lord doth confound the wise and bringeth about the salvation of many souls." (Book of Mormon | Alma 37:6 - 7)

As Paul writes the Corinthians, he teaches the same doctrine -

"For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent." (New Testament | 1 Corinthians 1:19)

He will destroy the wisdom of the wise because it seems as foolishness to them for -

"...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." (New Testament | 1 Corinthians 1:20 - 21)

Much like many in our day -

"For the Jews require a sign, and the Greeks seek after wisdom..." (New Testament | 1 Corinthians 1:22)

Therefore by small and simple means -

"...we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness..." (New Testament | 1 Corinthians 1:23)

It is not through the popular, rich, celebrities or the learned (wisdom of the world) that God works, but through the humble and meek -

"For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called:
27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;
28 And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are..." (New Testament | 1 Corinthians 1:26 - 28)

He does that so -

"...no flesh should glory in his presence." (New Testament | 1 Corinthians 1:29)

Or in other words, that man would glory in his own wisdom.
