Every year at this time, in San Pedro, Philipines, a bunch of people carry their crosses for a mile or so and then have themselves nailed to the cross to celebrate Easter. They guy in this picture has done this for the last 11 years, I think.
Why?
"to obey is better than sacrifice," says the Lord. A man can't pay for his own sins in the way Jesus did. Jesus paid the price for sin on His sinless body.
At best, this is just a very painful and dangerous wrong-headed way to worship, at worst it is ungrateful blasphemy. Ungrateful? yes. How? Jesus paid for the sins of these men when He was on the cross. They insult His sacrifice and its infinite value by mimicking it. It would be like having a loved one pay for an expensive meal for you and then going back and throwing a penny on the table and saying, "No, I'll pay."
