And again, “The Lord knows that the thoughts of the wise are futile.”
He adds Scripture's witness that the Lord knows the thoughts of the wise and that they are futile.
It reinforces the emptiness of worldly wisdom.
16Do you not know that you yourselves are God’s temple, and that God’s Spirit dwells in you? 17If anyone destroys God’s temple, God will destroy him; for God’s temple is holy, and you are that temple. 18Let 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. 19For the wisdom of this world is foolishness in God’s sight. As it is written: “He catches the wise in their craftiness.” 20And again, “The Lord knows that the thoughts of the wise are futile.” 21Therefore, stop boasting in men. All things are yours, 22whether Paul or Apollos or Cephas or the world or life or death or the present or the future. All of them belong to you, 23and you belong to Christ, and Christ belongs to God.
