I am not sure if I understand your question correctly, but I think you are asking about the religious discussion the grandmother has with the Misfit. On page 149 the old lady asks the Misfit whether he ever prays, to which he bluntly replies in his peculiar Southern dialect, "nome." This begins a conversation in which the Misfit reveals the extent to which he has thought about the figure of Jesus Christ, proving to have firmer religious convictions than the grandmother, for whom religion seems to be more a matter of social convention that of real belief. The Misfit belongs in a rich gallery of religious dissenters created by O'Connor in his stories and novels, and especially the character of Hazel Motes in Wise Blood, who founds the Church Without Christ, "where the blind don't see and the lame don't walk and what's dead stays that way." In his reply to the grandmother's agonizing but rather shallow calls to pray to Jesus, the Misfit expresses his inability to have faith and therefore his lack of belief in goodness as a means to achieve salvation:

"I wasn't there so I can't say He didn't," The Misfit said. "I wisht I had of been there," he said, hitting the ground with his fist. "It ain't right I wasn't there because if I had of been there I would of known. Listen lady," he said in a high voice, "if I had of been there I would of known and I wouldn't be like I am now" (p. 152)
