New King James Version (NKJV)
1 Corinthians 1
27 But God has chosen the foolish things of the world to put to shame the wise, and God has chosen the weak things of the world to put to shame the things which are mighty;
28 and the base things of the world and the things which are despised God has chosen, and the things which are not, to bring to nothing the things that are,
29 that no flesh should glory in His presence.
30 But of Him you are in Christ Jesus, who became for us wisdom from God--and righteousness and sanctification and redemption--
31 that, as it is written, "He who glories, let him glory in the Lord."
1 Corinthians 2
1 And I, brethren, when I came to you, did not come with excellence of speech or of wisdom declaring to you the testimony of God.
2 For I determined not to know anything among you except Jesus Christ and Him crucified.
3 I was with you in weakness, in fear, and in much trembling.
4 And my speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power,
5 that your faith should not be in the wisdom of men but in the power of God.
6 However, we speak wisdom among those who are mature, yet not the wisdom of this age, nor of the rulers of this age, who are coming to nothing.
