1 Corinthians 1:29 Meaning

27But 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;

28And 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:

29That no flesh should glory in his presence.

30But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:

31That, according as it is written, He that glorieth, let him glory in the Lord.
