Human wisdom sometimes sees the immediate cause of a problem but it does not see the root, which is always sin. It may see that selfishness is a cause of injustice, but it has no way to remove selfishness. It may see that hatred causes misery and pain and destruction, but it has no cure for hatred. It can see plainly that man does not get along with man, but it does not see that the real cause is that man does not get along with God. Human wisdom cannot see because it will not see. As long as it looks on God's wisdom as foolishness, its own wisdom will be foolish.  In other words, human wisdom itself is a basic part of the problem.
