1 Corinthians 1:18-21

1 Corinthians 1:18-21. For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent. Where is the wise? where is the scribe? where is the disputer of this world? Hath not God made foolish the wisdom of this world? For after that in the wisdom of God the world by wisdom knew not God,

You have only to study the history of the world at the time when Paul was writing, and you will see that the "world, by wisdom knew not God." It had made itself exceedingly philosophical and sage, but if you weigh its wisest conclusions you will find that they were only polished folly. There is nothing left us of all the wisdom of that period. Time itself has proved it: nay, has disproved it.
