“Any time you see a person engage in illicit sexual behavior, you can be sure that he or she is a cheater,” writes Jeffrey S. Black. “He or she wants sexual gratification without intimacy.” Likewise, Black tells us that people never leap into extreme forms of sin; they “drift” into them, and habits that were bad soon move to worse, even unthinkable.  How does such a person cease their cheating and drifting? Because sexuality is a spiritual act, not a purely biological one, the solution has to do with planting God’s Word in our hearts. Here Black shows us how the Bible reaches to the roots of sexual sin.
