A self-described "good Southern Baptist girl," Shelby Knox herself has pledged abstinence until marriage. When she finds that Lubbock has some of the highest rates of teen pregnancy and sexually transmitted diseases in the state, and her county's high schools teach abstinence as the only safe sex, she becomes an unlikely advocate for comprehensive sex education, profoundly changing her political and spiritual views along the way. "I think that God wants you to question," Shelby says, "to do more than just blindly be a follower, because he can't use blind followers. He can use people like me who realize there's more in the world that can be done." Here is a story for our times, where the combustible mix of politics, family and faith aren't as predictable as the red state/blue state divide would suggest.
