The fairytale life, the one that so many long after, usually goes something like this: fall in love with the perfect person, get married, and spend the rest of life happy and madly in love til death do you part- Carl and Ellie style. It seems like a few decades ago, this was the norm. Today, when I look around at society as a whole, I see people growing older either alone or in their second, third marriage and family dynamics that are dysfunctional, to say the least. Recent generations, particularly Gen X and onward, seem to have a mentality of discontent and entitlement and marriages are suffering for it. This is partially in correlation with the waning condition of broad-brush Christianity and disregarded morality, both of which are entirely unacceptable. Divorce, except for in the case of adultery, not only goes against the vows of "to death do us part" that two people take on their wedding day, but is also an act of disobedience to the law of God. Marriage is for keeps. No ifs, ands, or buts about it.
We live in an age in which people are both entitled and expect instant gratification. They need exactly what they want right now...until they don't want it anymore and they drop it like it's hot and move on to the next thing. Just look at the cell phone industry. A person gets that shiny new iPhone whatever and is super happy with it for only as long as it takes for the next newest and best model to come out.
The trouble is that people are treating their marriages in the same way. They fall "madly and deeply in love" with someone, get married, maybe have some kids, and then they get bored. Now, obviously there are other issues that could be going on, but one reason for impending divorce is pure boredom. So they throw away everything they share with each other (including their vows before God and the state).
Scripture is clear and without room or necessity for alternative interpretation when it comes to this matter. Mark 10:9 (KJV) says, "What therefore God hath joined together, let not man put asunder." and goes even further later with regards to remarriage in that a person who divorces his/her spouse and marries another person commits adultery against their first and true spouse. The bond between a man and woman at their wedding is an unbreakable bond made by God in heaven. It's not something you mess with or take lightly.
So many things in life are changing and change is often a good thing, but marriage is one thing that must remain static. It is a blessing that must not be messed with. As rare as it is seeming to become, I'm sure there are few things more wonderful than growing old with the love of your entire life.
