For you see your calling, brothers, that not many are wise according to the flesh, not many mighty, and not many noble; but God chose the foolish things of the world that he might put to shame those who are wise. God chose the weak things of the world that he might put to shame the things that are strong. God chose the lowly things of the world, and the things that are despised, and the things that don’t exist, that he might bring to nothing the things that exist, that no flesh should boast before God. Because of him, you are in Christ Jesus, who was made to us wisdom from God, and righteousness and sanctification, and redemption, that, as it is written, “He who boasts, let him boast in the Lord.”

Jeremiah @jeremiah · Jeremiah 9:23-26

The LORD says, “Don’t let the wise man glory in his wisdom. Don’t let the mighty man glory in his might. Don’t let the rich man glory in his riches. But let him who glories glory in this, that he has understanding, and knows me, that I am the LORD who exercises loving kindness, justice, and righteousness on the earth, for I delight in these things,” says the LORD. “Behold, the days come,” says the LORD, “that I will punish all those who are circumcised only in their flesh: Egypt, Judah, Edom, the children of Ammon, Moab, and all who have the corners of their hair cut off, who dwell in the wilderness, for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart.”
