Commandments Lead to Happiness
Matthew 5:32, "But I say unto you, That whosoever shall put away his wife, save for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery."
God's commandments are not intended to make us miserable -- they're meant for our own happiness. Satan's lie in the Garden of Eden caused Eve to question God's motives behind His command (Genesis 3:5).
Malachi 2:15 says God hates divorce. God doesn't hate the people who divorce. He hates the act of divorce because of the damage it does to people. God loves people.
Today, people see divorce as an easy way out of marital problems. But this is based on the misconception that the mate is the problem -- which is rarely the case.
People who blame their mate for their problems give in easily to divorce, thinking that a new partner will solve the situation. Yet second marriages have over twice the failure rate of first marriages. That's because we take ourselves and all our unresolved problems into the next marriage.
You can't control other people -- not even your mate. But through obeying the Lord, you can control yourself and have fullness of joy. God's commands tell us what will produce true happiness for us.
