Excerpt: 'The Year of Living Biblically'

Oct. 1, 2008— -- Most people try to live good lives, and many even try to stick to the Ten Commandments as closely as possible. But imagine taking every rule written in the Bible literally, not only rules such as honoring your parents, but things like blowing a horn on the first of every month and never cutting the corners of your beard.

Author A.J. Jacobs tried to live by every single precept in the Bible for an entire year, and documented his journey in his book, "The Year of Living Biblically." Please find an excerpt from it below:

As I write this, I have a beard that makes me resemble Moses. Or Abe Lincoln. Or Ted Kaczynski. I've been called all three.

It's not a well-manicured, socially acceptable beard. It's an untamed mass that creeps up toward my eyeballs and drapes below my neckline.

I've never allowed my facial hair to grow before, and it's been an odd and enlightening experience. I've been inducted into a secret fraternity of bearded guys -- we nod at each other as we pass on the street, giving a knowing quarter smile. Strangers have come up to me and petted my beard, like it's a Labrador retriever puppy or a pregnant woman's stomach.

I've suffered for my beard. It's been caught in jacket zippers and been tugged on by my surprisingly strong two-year-old son. I've spent a lot of time answering questions at airport security.

I've been asked if I'm named Smith and sell cough drops with my brother. ZZ Top is mentioned at least three times a week. Passersby have shouted "Yo, Gandalf!" Someone called me Steven Seagal, which I found curious, since he doesn't have a beard.

I've battled itch and heat. I've spent a week's salary on balms, powders, ointments, and conditioners. My beard has been a temporary home to cappuccino foam and lentil soup. And it's upset people. Thus far, two little girls have burst into tears, and one boy has hidden behind his mother.

But I mean no harm. The facial hair is simply the most noticeable physical manifestation of a spiritual journey I began a year ago.

My quest has been this: to live the ultimate biblical life. Or more precisely, to follow the Bible as literally as possible. To obey the Ten Commandments. To be fruitful and multiply. To love my neighbor. To tithe my income. But also to abide by the oft-neglected rules: to avoid wearing clothes made of mixed fibers. To stone adulterers. And, naturally, to leave the edges of my beard unshaven (Leviticus 19:27). I am trying to obey the entire Bible, without picking and choosing.

To back up: I grew up in an extremely secular home in New York City. I am officially Jewish, but I'm Jewish in the same way the Olive Garden is an Italian restaurant. Which is to say: not very. I attended no Hebrew school, ate no matzoh. The closest my family came to observing Judaism was that paradoxical classic of assimilation: a Star of David on top of our Christmas tree.

It's not that my parents badmouthed religion. It's just that religion wasn't for us. We lived in the twentieth century, for crying out loud. In our house, spirituality was almost a taboo subject, much like my father's salary or my sister's clove-cigarette habit.

My only brushes with the Bible were brief and superficial. We had a next-door neighbor, Reverend Schulze, a kindly Lutheran minister who looked remarkably like Thomas Jefferson. (By the way, Reverend Schulze's son became an actor and, oddly enough, went on to play the part of the creepy priest on The Sopranos .) Reverend Schulze told great stories about college sit-ins during the sixties, but whenever he started talking about God, it just sounded like a foreign language to me.

I attended a handful of bar mitzvahs where I zoned out during services and spent the time trying to guess who had bald spots under their yarmulkes. I went to my paternal grandfather's funeral, which was, to my surprise, presided over by a rabbi. How could the rabbi eulogize a man he'd never met? It was disconcerting.

And as far as childhood religion, that was about it.

I was agnostic before I even knew what the word meant. Partly, it was the problem of the existence of evil. If there is a God, why would He allow war, disease, and my fourth-grade teacher Ms. Barker, who forced us to have a sugar-free bake sale? But mostly, the idea of God seemed superfluous. Why do we need an invisible, inaudible deity? Maybe He exists, but we'll never know in this life.

College didn't help my spiritual development. I went to a secular university where you were more likely to study the semiotics of Wicca rituals than the Judeo-Christian tradition. And when we did read the Bible, it was as literature, as a fusty, ancient book with the same truth quotient as The Faerie Queene .

We did, of course, study the history of religion. How the Bible has been the force behind many of humankind's greatest achievements: the civil rights movement, charitable giving, the abolition of slavery. And how, of course, it's been used to justify our worst: war, genocide, and the subjugation of others.

For a long time, I thought that religion, for all the good it does, seemed too risky for our modern world. The potential for abuse too high. I figured it would slowly fade away like other archaic things. Science was on the march. Someday soon we'd all be living in a neo-Enlightenment paradise where every decision was made with steely Spock-like logic.

As you might have noticed, I was spectacularly mistaken. The influence of the Bible -- and religion as a whole -- remains a mighty force, perhaps even stronger than it was when I was a kid. So in the last few years, religion has become my fixation. Is half of the world suffering from a massive delusion? Or is my blindness to spirituality a huge defect in my personality? What if I'm missing out on part of being human, like a guy who goes through life without ever hearing Beethoven or falling in love? And most important, I now have a young son -- if my lack of religion is a flaw, I don't want to pass it on to him.

So I knew I wanted to explore religion. I just needed to figure out how.

The germ of the idea came from my own family: my uncle Gil. Or ex-uncle, to be exact. Gil married my aunt and divorced her a few years later, but he remains the most controversial member of our family. If the rest of my relatives are ultrasecular, Gil makes up for it by being, quite possibly, the most religious man in the world. He's a spiritual omnivore. He started his life as a Jew, became a Hindu, appointed himself a guru, sat for eight months on a Manhattan park bench without speaking, founded a hippie cult in upstate New York, turned into a born-again Christian, and, in his latest incarnation, is an ultra-Orthodox Jew in Jerusalem. I may have missed a phase -- I think he was into Shinto for a bit. But you get the idea.
