Someone asked me recently what I thought the number one lesson of marriage is. They were particularly interested what the number one lesson of marriage might be that I've learned personally. My response went something like this: "Care about very little".
Puzzled, they pressed me: "What do you mean?"
"Well," I continued, "say you care about how the toothpaste should be squeezed. Some people care a lot that it be squeezed properly. Or you might care about if the toilet roll hang a certain way. Seriously, some people like the roll to hang over the top and some from the bottom. Or you might care about when you should open Christmas presents. Your husband or wife might like to do it on Christmas Eve when you think that's an abomination before the Lord. Presents on Christmas morning for you.
"You might care about what kind of car to buy. Or what color it should be. You might care about the square footage necessary for your house. You might care about what color to paint the walls of your bedroom. Or the color of your bath towels. You might care about the quality and diversity of your family meals. Or if your vacations are exotic enough.
"In short, you might care about a lot of things. In marriage, don't."
Here's what I've learnt: In every single thing you care about you have the potential for argument, stress and frustration. So my advice is this: Don't care about any of this. Don't care about cars, home decor, paint, toothpaste, family rituals, food, or toilet paper. Just don't care. Free yourself up to care about and invest in what really matters. You'll be happier and fight much less.
In theology there's a term called "adiaphora". It's a term used to refer to things which, theologically speaking, we are indifferent to. We, in a sense, don't care about these issues. We won't let differences on these points be a source of conflict or division. My marriage advice was about adiaphora: Become indifferent to trivial things. Don't fight about inconsequential stuff.
My advice for the church is the same: Expand the space of adiaphora. Stop caring about inconsequential stuff. Focus on the matters of importance. People are starving to death today. Someone at work is lonely. An innocent man is sitting in jail. Think Matthew 25 or Romans 8 or Romans 12 here.
Just don't fight over how you squeeze the toothpaste.
