What is the significance of Christianity and faith in this novel?

Religion is in many ways mocked by As I Lay Dying. The story is an ironic twist of the classic quest – a journey without a purpose, confession without redemption. Divine justice is never just, as immoral men are rewarded with good luck while struggling devotees are destroyed with bad. The central religious figure of the novel – a minister – is a hypocritical adulterer who illegitimately fathers a son while preaching chastity and morality......Religious characters in the novel believe that, because death is a reward, it provides the motivation to live one’s life well. Get done everything you need to get done, and you’ll be granted…death.
