In this chapter, St. Paul builds on that idea that we are all united in Christ. He points out that he does not depend on persuasive words. Instead he relies on heavenly wisdom which comes from the Holy Spirit when we build our relationship with God. He also introduces the natural man while in the next chapter he discusses the carnal man. Here, he explains that the natural person cannot understand heavenly wisdom, because they only rely on their own wisdom and that of the world.
