1 cor 3

Do not deceive yourselves. If any one of you thinks he is wise by the standards of this age, he should become a "fool" so that he may become wise. For the wisdom of this world is foolishness in God's sight. As it is written: "He catches the wise in their craftiness" and again, "The Lord knows that the thoughts of the wise are futile." So then, no more boasting about men! 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 of Christ, and Christ is of God.

true, like a smack in the head.
