⁶ Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought:

¹² Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.

¹⁸ Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise.

¹⁹ For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
