I believe a Christian who is involved in charitable work or a ministry in their church is less likely to commit a sexual sin. There is something about being held accountable to one another, and there is certainly accountability in the church (Matt 18:15-20). Besides, that might be the place to meet a godly Christian man or woman. That may lessen the chances of sexual immorality occurring (we would hope, at least), because just as “Bad company ruins good morals” (1st Cor 15:33), good company builds morals.
