1 Corinthians 3:18-20

1 Cor. 3:18 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.

1 Cor. 3:19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.

1 Cor. 3:20 And again, The Lord knoweth the thoughts of the wise, that they are vain.
