What is the main conflict in A Fine White Dust by Cynthia Rylant?

Every person must make personal decisions about God, religion, and church rituals sometime while working toward maturity. In this story Pete attends church even though his parents do not. He realizes that he has a searching need for spiritual fulfillment when a transient revival preacher comes to town and calls on Pete to help him save sinners. Pete becomes so absorbed by this preacher that he is willing to leave his parents and follow the call. Since Pete's parents do not share his zeal, he is at times ashamed that they do not attend church and he feels an obligation to get them to change.
