People in Jesus' time had a bad attitude about marriage, just like today. They seemed to think it was a person's right to divorce whenever they decided they wanted to, just like today. But Jesus corrected this by pointing them toward the nature of marriage and showing that marriage it a holy and wonderful union that God Himself has created. Jesus takes away their excuses and calls them to get back to the heart of marriage rather than seeking excuses to divorce. It was a message people desperately needed to hear at the time, just like today.
