1) John Marrant's narrative differs from typical slave narratives as it focuses more on his spiritual and religious experiences than providing an emotional account of his time in bondage.
2) The narrative can be seen as subtly legitimizing slavery as Marrant takes a submissive position and distances himself from his black identity in order to be accepted by white people.
3) When facing execution, Marrant asks his executioner for permission to pray, showing that both God and the executioner hold power over him as his master. The narrative reinforces the use of Christianity to justify white supremacy and slavery.
