Extreme Makeover

After A. J. Jacobs spent a year reading the entire Encyclopaedia Britannica for his book "The Know-It-All," he figured he had the yearlong experiment thing down. How much harder could it be to follow every rule in the Bible? Much, much harder, he soon discovered, as he found himself growing his beard, struggling not to curse and asking strangers for permission to stone them for adultery. Jacobs spent the year carrying around a stapled list of the more than 700 rules and prohibitions identified in the Good Book, and also consulted with religious leaders and spent time with the Amish, Hassidic Jews and Jehovah's Witnesses. He spoke to NEWSWEEK's Jennie Yabroff about his experience and his new book, "The Year of Living Biblically" (Simon & Schuster), which goes on sale Oct. 9. Excerpts:

NEWSWEEK: It's been a little over a year since your experiment ended and you shaved your beard. How's the life of sin?
A. J. Jacobs: It's all right. I miss my sin-free life, but I guess I was never sin free. I was able to cut down on my coveting maybe 40 percent, but I was still a coveter. Flat-screen TVs, the front yard of my friend in the suburbs, a better cell phone, higher Amazon rankings. And that's not to mention coveting my neighbor's wife. I live in New York, I work in publishing, so there's a lot of coveting, lying and gossiping.

What, if any, rules are you still following?
I'm not Gandhi or Angelina Jolie, but I made some strides. The experience changed me in big ways and small ways. There's a lot about gratefulness in the Bible, and I would say I'm more thankful. I focus on the hundred little things that go right in a day, instead of the three or four things that go wrong. And I love the Sabbath. There's something I really like about a forced day of rest. Also, during the experiment I wore a lot of white clothes, because Ecclesiastes says let your garments always be white, and I loved it, so I look like Tom Wolfe now. Wearing white just made me happier. I couldn't be in a bad mood walking down the street looking like I was about to play in the semifinals at Wimbledon. One thing I learned is that the outside affects the inside, your behavior shapes your thoughts. I also really liked what one of my spiritual advisers said, which was that you can view life as a series of rights and entitlements, or a series of responsibilities. I like seeing my life as a series of responsibilities. It's sort of, "Ask not what the world can do for you, ask what you can do for the world."

There seems to be a great interest in religion and fundamentalism in our culture right now. Why do you think that is?
As far as I can see it, it goes in waves. Now it seems like the third great awakening. Is that right? I've forgotten my encyclopedia knowledge. But I do think we're going through a wave right now. You certainly see it with Islam. I think it's ebbed a little bit because the atheist movement is creating backlash against the religious movement, so it might have peaked a year ago. But it's certainly the defining issue of our time. I hope the book will appeal to both the sacred and the profane.

Are you a more religious person as a result of this experiment?
Well, I don't want to give away the ending, but let's say I started the year as an agnostic, and now I am a reverent agnostic. Whether or not there is a God, I believe in sacredness. Rituals can be sacred, the Sabbath can be sacred however you choose to observe it.

Which is the greater learning tool, the Bible or the encyclopedia?
That's a tough question. The Bible project was a lot more difficult than the encyclopedia project. The Bible affected every single part of my life, it affected the way I walked, the way I dressed, the way I hugged my wife, the way I ate. The year was the most extreme makeover of my life. In terms of which is the better learning tool, the encyclopedia does contain a lot of biblical passages in the different books, so it might contain most of the Bible in it.
