I first came across St. Augustine's "Confessions" when I was a freshman in college. It was a monumental experience in terms of both the content of his writing and the freshness and relevance of his writing style. After re-reading them again recently, I am still struck with how contemporary the book feels. Aside from many of its 4th century particularities, the concerns that St. Augustine had and the way he frankly and honestly dealt with them could be lifted from almost any contemporary tell-all autobiography. The biggest exception is the fact that "Confessions" is a quintessentially and irreducibly a religious text, and in an age when religious considerations are largely pushed towards the margins of their life stories, it is refreshing and uplifting to see what would a life look like for someone who took them very seriously and committed himself to reorganizing one's whole life around the idea of serving God wholly and uncompromisingly. "Confessions" is a very accessible text, and for the most part it does not deal with theological and philosophical issues. The exception is the latter part of the book, which are almost exclusively dedicated to those topics. You may want to skip those at the first reading, but I would encourage you to read them nevertheless. Maybe the very inspiring and uplifting story of St. Augustine's conversion to Christianity can lead you into deeper considerations about your faith or the meaning of life in general. I cannot think of a better introduction to those topics than "Confessions," nor of a better guide than St. Augustine.
