1 Corinthians 3:18

16 Do you not know that you yourselves are God’s temple, and that God’s Spirit dwells in you?

17 If anyone destroys God’s temple, God will destroy him; for God’s temple is holy, and you are that temple.

Let no one deceive himself. If any of you thinks he is wise in this age, he should become a fool, so that he may become wise.

19 For the wisdom of this world is foolishness in God’s sight. As it is written: “He catches the wise in their craftiness.”

20 And again, “The Lord knows that the thoughts of the wise are futile.”

Do read the surrounding verses too, because the context often says more than a single verse.
