Neither Paul nor any other legitimate church leader in 2000 years has ever found it necessary (or even helpful) to use streetwise sex education—not as an evangelistic strategy, and certainly not as a means to sanctification for people already overwhelmed with sex-talk from a corrupt culture. Adopting the world’s obsession with sex and filthy talk cannot possibly have a sanctifying effect, because the strategy itself is unholy.
The notion that degenerate subcultures and sexually-addicted people cannot be reached without “learning to speak their language” is an absolute fallacy. Grace Church is seven miles from Hollywood, in the heart of Southern California, in a carnal, pleasure-mad culture well-known worldwide for everything but healthy spiritual values. No city in America is more “unchurched” than our valley, which houses more than three million people. The people of Grace church are reaching friends and neighbors in every imaginable subculture—from ex-cons to ex-Catholics to people in the entertainment industry. We baptize new believers virtually every Sunday night. It is neither necessary nor helpful to inject explicit sexual references into the conversation in order to reach people from such a culture. God draws them to Christ through the gospel.
