For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than men, and the weakness of God is stronger than men.
For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth. 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."

God hath chosen the foolish things of the world to confound the wise, and the weak things to confound the things which are mighty. He has chosen the lowly things, the despised things and the things which cannot be destroyed as the things that are. Therefore, not many men wise according to the world, not many mighty, not many noble are called. God in His sovereignty takes up that which is foolish and weak to manifest His power. How fully this is evidenced by experience. And the believer is always in the safe place, if he is in the place of humility, self-effacement and weakness. It is all of God, and all in Christ, and nothing of us or in ourselves. Christ is the wisdom of God.

The Aposle Paul puts it another way: Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool that he may become wise. For the wisdom of this world is folly with God. For it is written, "He catches the wise in their craftiness," and again, "The Lord knows the thoughts of the wise, that they are futile." So let no one boast in men. For all things are yours, whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all are yours, and you are Christ's, and Christ is God's. 1 Corinthians 3:18-23.

The Corinthians were ignoring the wisdom of the Spirit being seduced by the wisdom of the world, which is foolishness with God. They had made them useless vessels for God, bearing no fruit by their carnal spirit, trusting and glorifying in themselves and yet in God’s gracious purpose as revealed by the Spirit of God all things were theirs. Paul, Apollos and Cephas were the chosen instruments of God's blessing. As believers they had all things and belonged to none but Christ and through Christ to God Himself. What of yourself: is your self image; your identity – is it in Christ or in yourself which will fail and crumble?
