1 Corinthians 1:27-31 – “But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong; God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, so that no human being might boast in the presence of God. And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption, so that, as it is written, “Let the one who boasts, boast in the Lord.”
1 Corinthians 1:18 – “For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.”
1 Corinthians 2:14-15 – “The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. The spiritual person judges all things, but is himself to be judged by no one.”
1 Corinthians 1:27 – “But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong;”
