Driving Nails with a Moonstone

I have a moonstone sitting on my desk.  It’s an ordinary-looking hunk of milky-white rock, smaller than a quarter, and a little investigation confirms the ordinariness of it.  Moonstone is feldspar, which is arguably the commonest rock on the face of the earth.  Maybe 60% of the earth’s crust is feldspar.  Even the name indicates its commonness: it’s from the German feld (field) and spath (rock without ore) — in other words, “worthless field rock.”

Which is exactly what it looks like…unless the light hits it just right.  As I sit at my desk, the moonstone is sitting at just the right angle so that the light from the window makes one end of it glow a brilliant blue.  If I hold it up, domed side toward me, I’ll see a reddish-orange plane deep inside the stone, if I can catch the light just so.  The effect, in both cases, is called adularescence, and occurs because two different types of “worthless field rock” have intergrown in layers, internally reflecting and refracting the light.  But you have to get the angle just right to see it–any little movement makes the colors change and shift like a tiny aurora borealis, or vanish altogether, and it’s back to being an irregular milky-looking lump of rock.

So that’s the answer to the question, “What is it?”  But…why is it?  What sort of world do we live in, where God takes two different types of the commonest rock on earth, and combines them to make a gemstone?


What sort of world is it, where God takes two different types of ordinary people and combines them to make a reflection of Christ and His Church — a marriage?

The sort of world where the ordinary stuff was spoken out of nothing, is sustained by that same Word, and is, well, magical.  It’s the sort of world where an irregular lump of white rock is a means of grace, an aurora borealis that I can carry in my pocket to remind me how I should treat my wife.


Hematite is not as visually interesting as moonstone.  Even with a high polish on it, it’s still a uniform, opaque, reflective grey.  But if you can get it hot enough, you can separate out the impurities, and shoot air through it to make steel.  Steel makes all sorts of useful things: springs, hinges, hammers…you name it.  I have a little hammer I inherited from my grandmother.  It can’t weigh more than 5 or 6 ounces, but she was a small woman, and she wanted something she could keep in a kitchen drawer for small household tasks: driving a tack, tapping in a small nail to hang a picture, like that.  I also have a 20-ounce Estwing straight claw hammer with a steel shaft and a blue rubber handle.  It was a birthday gift, back when I was doing construction work.  I wanted something that would suit the type of work I was doing, and that was it.  That hammer swung like it was part of my arm, and I could sink 16-penny nails, tap-Bang-BANG.   If I’d had to use Grandma’s kitchen hammer, I could drive maybe five nails a day.

It’s the sort of world where having the right tool for the job makes a difference.


I still have that blue-handled Estwing.  I’ve owned it for more than half my life, and it’s stained and a little rusted from use and abuse, but it still works as well as it did the day I first picked it up.  It lives in my tool kit, which lives in my bedroom closet.

Suppose I’m out somewhere without my tools and I need to drive a big nail?  A quick inventory of my pockets turns up a cell phone, notepad, two pens, wallet, pocketknife, and that little chunk of moonstone.  Not promising, is it?

Suppose I decide, well, rock is hard like a hammer, let’s give that a try.  So I try to drive a 16-penny nail with that little piece of moonstone.  How is that going to work out?  When I’m done, the nail won’t have moved very much.  On the other hand, the stone will be chipped and cracked at least, if not shattered into pieces, and its value as a gemstone lost.

It’s the sort of world where trying to substitute one means of grace for another often doesn’t do the job, and damages your ability to enjoy what you do have.

    I guess that is another reason for the Body of Christ – eyes are about as good at walking as moonstones are at hammering. 🙂 Oh for the wisdom not just to use the right tool for the right job but to know what He has made us for, gifted us for and blessed us with so that we don’t smash ourselves (or someone else for that matter!) and destroy the gleaming gems He has woven into us.
    Thanks Tim – this was another one of those posts that simmered gently for a few days and produced ideas rather rich in their complexity.

    You’re more than welcome, and thank you for your kind words. I hadn’t thought to turn the analogy in the direction of the Body — thank you for that. It’s so true. I wasted a lot of time some years back trying to be a full-blown evangelist before I figured out what my gifting was. (And of course, I’m still exploring and learning there; it seems to be a moving target as I get older.)

    Tim, you lost me on this one. I was hoping someone else would ask first so I didn’t have show my lack of perception but it ain’t happening. So what’s an example or two of substituting one means of grace for another?

  4. Tim Nichols says:


    You need never feel bad for asking, brother. Always welcome.

    One example would be driving a nail with a moonstone… 😉 Seriously, though, any situation where you’re trying to stretch one means of grace to cover something it’s not designed to do.

    • — The Christian who says, “I don’t need all these other people; I just need to walk with God myself, and everything will be fine,” and therefore writes off Christian fellowship. God says that it’s not good for man to be alone, and ultimately gives us the Body of Christ; this guy is refusing the blessings of fellowship with God’s people, and trying to cover his lack by relying on fellowship with God. Of course, if he’s in a Robinson Crusoe situation, then God has providentially placed him there, and that’s fine. But if he’s doing it voluntarily, God may not honor that silliness.
    • — The reverse sometimes happens in a marriage, where one spouse will begin to depend on the other for the security, comfort, love, insight, etc. that only God can give. God gives marriage, and your spouse in particular, for blessing, but when you begin to look to her for things that you should be getting from God, that won’t be good for your marriage or your walk with God.
    • — A believer who says “Hearing God’s Word is the highest form of worship, so what do I need with singing?” Well, there are certain things singing is designed to do to you. He’s assuming that he can get all those things from teaching, and that may turn out not to be the case.

    Is this helping to answer your question?

  5. David says:

    Yep, got it. Thanks. In my former corner of the world, I kinda think that Bible study / doctrine was just about the only tool in the kit. Or maybe it was the all-in-one tool that could substitute for anything that was lacking.

  6. Tim Nichols says:

    I ministered in a similar community for a number of years. Truth be known, though, an awful lot of people in the Bible college/seminary scene work on that same assumption, although most know better than to say so out loud.
