When I went to Israel, it was a little disorienting, because there are so many people who look crazy and were dressed like me. There, I was just one of the apocalyptic crowd.

My goal? To test out every diet and exercise regimen on planet earth and figure out which work best. I sweated, I cooked, I learned to pole dance. In the end, I lost weight, lowered my cholesterol and doubled my energy level. I feel better than I ever have.

The whole bible is the working out of the relationship between God and man. God is not a dictator barking out orders and demanding silent obedience. Were it so, there would be no relationship at all. No real relationship goes just one way. There are always two active parties. We must have reverence and awe for God, and honor for the chain of tradition. But that doesn't mean we can't use new information to help us read the holy texts in new ways.

I tried the paleo diet, which is the caveman diet - lots of meat. I tried the raw food vegan diet.

Whether or not you want to, of course, is the idea.
