Now viewing scripture range from the book of 1 Corinthians chapter 3:18
through chapter 3:20...
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.
20 And again, The Lord knoweth the thoughts of the wise, that they are vain.
