Ten Thousand Repairs You Never Felt

Every single day, the DNA inside your cells sustains somewhere between ten thousand and one hundred thousand points of damage. Ultraviolet light, metabolic byproducts, simple copying errors — the assaults are relentless and constant. By all rights, your genetic code should be in ruins by lunchtime.

But it is not. And here is why.

In the 1970s, biochemist Tomas Lindahl discovered something remarkable — work that would eventually earn him the Nobel Prize in Chemistry in 2015. He found that your cells come equipped with an elaborate repair system. Enzymes patrol the double helix like tireless watchmen, snipping out damaged sections, filling in correct sequences, and stitching the strand back together. This happens thousands of times a day, in every one of your thirty-seven trillion cells, and you never feel a thing.

You did not build this system. You did not earn it. You cannot improve upon it by trying harder. It was simply there before you drew your first breath, working on your behalf while you slept.

Grace operates the same way.

Long before you recognized the damage sin had done, the Almighty was already at work mending what was broken. His mercy does not wait for you to diagnose the problem. It does not require your awareness to begin its restoration. Grace, like those faithful enzymes, is already moving through the deepest parts of who you are — quietly repairing what you did not even know was torn.

You cannot earn that. You can only receive it.
