Marriage is a definitive moral statement.  Regardless of how confused Americans are about any number of ethical issues, people still understand that marriage is unique to two people and should not be broken.  The recent fall of Tiger Woods supports this: no major commentator has come out in support of his actions.  Research suggests that allowing opportunity and vulnerability is what causes people to sin.  As Dr. Mohler notes on today’s program, the apostle Paul writes in the book of Romans that sin overtakes us when opportunity presents itself.  Christians must be careful to set boundaries, guard their hearts and hold their actions accountable to other Christians.
