Describe how Msimangu's sermon affects Kumalo and changes his mood?

Msimangu gives a sermon to the blind there in which he quotes from the Bible: "I the Lord have called thee in righteousness . . . To open the blind eyes to bring out the prisoners from the prison / And them that sit in darkness of the prison house." Kumalo knows that Msimangu is speaking to him at this moment. After the sermon, Kumalo goes to Msimangu and says that he is recovered.

During the visit to Ezenzeleni, Paton compares the state of Stephen Kumalo through the chapter to the blind at Ezenzeleni. Kumalo enters Ezenzeleni metaphorically blind, but leaves the area with a newfound vision. Paton imbues this with intense Biblical imagery, the most explicit of this contained in Msimangu's sermon, which is in many ways the impetus for Kumalo's conversion. Like numerous Biblical figures, Kumalo is redeemed by suffering and receives a new and greater vision from it.
