How does Jero get converts?

Brother Jero is the main character of the play and the leader of his self-organized Brotherhood of Jero. He is a “suave” and false prophet who preaches to the community in hopes of attracting more followers. Although claiming to have been born a prophet, Jero frequently admits to his acts of deception and above all else desires to be held in high esteem as "Brother Jero, Articulate Hero of Christ’s Crusade."
