Sexual Sin is Everywhere
A 2006 report on NPR said that 80 percent of Americans are sexually active by the age of 20, and only 20 percent of women marry as virgins. Furthermore, cohabitation has increased 72 percent between 1990 and 2000, and the cohabitation rate increased ten-fold between 1960 and 2000. Fully 41 percent of Americans will cohabitate at some point during their life.
Many people who attend Mars Hill Church come with sexual sin in their distant or recent history. This includes unmarried people who have been guilty of fornication, as well as married people who have been guilty of adultery. Thankfully, Jesus died and rose to forgive such sin, thereby enabling us to put these sins to death in our own lives by His empowering grace. Furthermore, according to Scripture, one of the defenses against sexual sin is getting married (1 Corinthians 7:1–2) and having frequent and free marital intimacy so that sexual desires have a holy outlet.
