The White Post

“And be not conformed to this world: but be ye transformed by the renewing of your mind.” — Romans 12:2 (KJV)

Chesterton had a simple but brilliant picture for why good things need constant care. Some people think that if you just leave things as they are, they will stay the same. Chesterton says no:

“If you leave a white post alone it will soon be a black post.”

Dirt, weather and time will turn it grey and then black. If you want it to stay white, “you must be always painting it again”. Or, as he puts it, “if you want the old white post you must have a new white post.”

This is true of everything good. Friendships fade if you don’t keep investing in them. Habits of prayer slip if you don’t keep returning to them. Fairness in a school or a country slowly erodes if nobody keeps standing up for it.

Chesterton says this is why Christianity is, in a way, revolutionary. It doesn’t just accept things as they are. It keeps calling people and societies back to what is good, again and again. He notes that people usually suffer not under ancient tyrannies but under new ones that grow up quickly when nobody is watching.

And he gives a crucial point about progress. You can only make real progress if you have a fixed idea of what “better” means. If your idea of good keeps changing, you can never tell whether you are improving. Christianity gives a fixed picture of goodness: Jesus himself.

Paul says the same in Romans 12: don’t just drift along with the world, but be transformed by the renewing of your mind. Renewal isn’t a one-off. It’s daily repainting.

What white post in your life is starting to go grey? Maybe it’s your prayer life, a friendship, your honesty, or how you treat your family. Don’t wait until it’s black. Pick up the paintbrush today.

One thing to do this week: identify one “white post” in your life that has been fading: a friendship, a habit or a value. This week, “repaint” it with one deliberate action, and plan how you will keep repainting it.
