I recently heard this emotional argument:
There are 54 million Americans who are currently divorced or have been divorced and remarried. Because so many people are affected by divorce, we cannot possibly consider teaching so many people that the only cause for divorce is for sexual immorality and the only God-approved reason for remarriage is if your spouse cheated on you or died (Matthew 5:31-32; Matthew 19:6-9; Romans 7:1-3; 1 Corinthians 7).
When does the number of people violating God’s law ever affect or change how we should interpret God’s law? Should we reconsider the command against homosexuality (1 Corinthians 6:9) simply because millions of Americans are engaging in the activity? Should we reconsider the command against stealing (Ephesians 4:28) since there are so many crimes of theft? How dare anyone suggest or preach that because there are so many people affected by a particular sin that this should cause us to reconsider God’s stance on the topic? We would not make such a rationalization for any other sin. So why make such a rationalization for divorce and remarriage?
Perhaps the easy answer is to teach people to quit violating God’s law if they want to have a good life now.
