John+Donne's+higher+purpose

John Donne's higher purpose is to write a poem, from the point of view of a christian, about sin and about confessions. One can tell that the narrator is haunted by what he did or the sin he committed. He is asking his god for peace from whatever may be haunting him. One thing he really is trying to put across is that often sins will come back to haunt you, thus, what comes around goes around. John Donne also shows that the christian religion is about heaven and hell and about how you really should help people or at the very least not harm them, or one may find themselves in a very unhappy place.
