Some people consider themselves true believers. And then, there are the snake handlers. Whether or not you think they're deeply devoted, nuts, or both, you can't say they don't have guts. In this exclusive clip from the new Nat Geo series, "Snake Salvation" (debuts tonight at 9:00 p.m. and 9:30 p.m. ET), we get a first glimpse of what pastors Jamie Coots and Andrew Hamblin consider a mission from God -- snake handling. 

On the show, we learn that some devotees of snake handling (there are only 100 churches devoted to the practice in the U.S.) believe they will go to hell if they don't toss around venomous creatures, and are often considered in violation of the law for the practice -- plus, going to the hospital for a snake bite is defying God's will. So much for just slipping a twenty into the collection plate.
