At the most fundamental level Augustine's Confessions is Augustine of Hippo sharing his story of conversion to Christianity. This story, however, doesn't fit neatly into what one might typically imagine when contemplating the process by which a future saint finds God. Indeed, a large part of what makes Augustine's journey so delightful is that in many ways it was a very personal and common project: finding one's place in the world.
