Why is Faith so Important? (1 Cor. 2:1-5)

We believe that one is righteous before God by taking hold of Christ through faith.  Paul says that he desires to know nothing except Jesus Christ and Him crucified.  Does this mean that Paul is denying Christ’s resurrection?  Does this mean that Paul is teaching us not to learn from wise men in the past nor to look at any other Scriptures?  What does Paul mean by this strong statement, “Jesus Christ and him crucified?”
