Stones Cry Out has a good reminder about the dangers of immorality. Even with 100% condom use, 30% of the people in one study acquired the cancer-causing human papilloma virus (HPV). Condom use is proclaimed as a successful way to “reduce risk,” but sexual morality seems like the only reasonable way, in my opinion.
Abstinence works. Morality works. Latex might not.
Some people engage in immorality and manage to avoid STDs and other obvious physical complications, but genuine spiritual and social harm is still there. How great the need to teach people to hold the higher standards that God has given us, and to remain or become pure and clean before Him. How great the need to teach the power of repentance and the hope it brings to those many who fall.
