This past weekend, I presided at a wedding. As always, the ceremony is a time of joy and celebration. The bride and groom look their best, and everything that happens point to one thing: happiness and smiles.

So, when I stand before the just-about-to-be-married couple, speaking to them (and to those who are gathered), I want to say nice, happy things. I want to add to the festive spirit. And I do.

But I also want to say: Do you really know what you’re doing? Are you really ready for this? Because your vows are real. This is the real deal. And marriage will be one of the most difficult things you ever do.

Now, that’s not what I say. At least not in so many words. But I do say this:

We live in a world that can be cynical about marriage. There are those who doubt that a couple can spend a lifetime of love together. That instead of finding freedom in marriage, it ends up being a shackle.

As someone once sarcastically said, “Marriage is a wonderful institution. But who would want to live in an institution?”

But that’s not how the Bible sees it. In fact, from the very beginning, God makes man, and then provides man a helper; an equal, a partner for the journey. For life – with all its challenges and disappointments, with all of its joys and pleasures – is meant to be shared. The good, the bad, and the ugly. The days your heart aches and the days your heart skips a beat. The day you get a promotion, AND the day you lose your job.

And the way to grow stronger through Whatever comes your way – is by firmly holding onto each other.

In other words, marriage is hard. In part, because life is hard. And there’s a reason that in our marriage vows, we don’t say: “I do, if I feel like it,” or “I do, as long as it works for me,” or, “I do, as long as it’s not too difficult.” That’s not how marriage works. That’s not how life works. The way through the difficult times is to walk through those difficult times together.

I recently read a long article, published by the New York Times, that talked with couples who are practicing what is called “open marriage.” If you’re not familiar with the concept, it’s pretty much what it sounds like. Open marriage is where a couple “opens” their marriage to other intimate relationships, to other lovers. And the article is full of people giving reasons why this makes things better, at least in their minds.

While most of us can come up with a number of reasons why open marriage doesn’t work and doesn’t make sense, perhaps it’s a perfect sign of our times — where so many believe that life is found, not in our commitments, but in our freedoms. That is to say: real life is found by always keeping our options open.

The preacher and writer John Ortberg contends that so many who live for so much freedom end up coming to the end of their lives, and they can’t remember what they did with all the money they were free to make and spend. They can’t remember what they did with all that time they were so busy protecting. They can’t remember what happened to all those relationships that they were so free to exit. In the end, by keeping their options open, and by not fully committing to anything, they end up with a life committed to nothing.

Then Ortberg makes this vital point: It’s not in our freedom, but in our commitments, that we find ourselves.

What an absolutely counter-cultural argument, one that is sure to mystify many. But what a vital truth that is spot on. In a world where so many run from commitment — whether it’s in marriage, or parenting, or a job, or church, or just settling in one place to be a blessing to those around us — it’s really true: real life is found, not in what we keep open, but what we hold onto. In the end, we are defined, we are shaped, we become: not by what we run from, but what we commit to.
