What is the difference between man’s wisdom and God’s wisdom?

What then is the difference between man’s wisdom and God’s wisdom? One way to answer this question is to notice from 1 Corinthians 1:17 and 1:23 that human wisdom nullifies the meaning of the cross of Christ and God’s wisdom upholds the meaning of the cross. Paul says that if he had come preaching “in wisdom of word” (the literal translation) “the cross of Christ would ... be made void.” And he adds that “the Greeks search for [human] wisdom” and therefore regard the preaching of the cross as “foolishness.” So there is something about “human wisdom” that nullifies the cross by regarding it as foolishness, when, in fact, the cross is “the wisdom of God” (1 Corinthians 1:24).
