Today, nearly half of American high schoolers, aged 14 to 18, are sexually active, according to a Centers for Disease Control survey. Even Christians aren’t waiting until marriage. Among unmarried adult evangelicals under 30, 8 in 10 have had sex.

Somebody has to say it: Our approach isn’t working, and it’s time to rethink “the talk.” It’s time to expand the conversation into territory where many evangelical parents dare not go.

The familiar Christian parenting mantra of Proverbs 22:6 tells us that if we “start children off on the way they should go, when they are old they will not turn from it.” For sex education, many evangelical moms and dads hold to this verse, teaching their kids to “just say no” and trusting they’ll stick to it.
