1 Corinthians 1:26-29
26 For you see your calling, brethren, that not many wise according to the flesh, not many mighty, not many noble, are called. 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.
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
1 Corinthians 1:30-31
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.”
2 Corinthians 10:17
But “he who glories, let him glory in the Lord.”
But God forbid that I should boast except in the cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world.
