Sermon Illustrations
Posted by Douglas on Apr 02, 2013

A year ago I went to see my dentist and he said to me, "Doug, you have great teeth. They are solid, the gums are good, everything looks great!"

This year I went back for my checkup and he said, "Oh, Doug, you have two big cavities, right between the teeth." Long pause... "Have you been flossing?"

Ouch. Of course -- that task I know I'm supposed to do every day, but I don't. Flossing helps to clean out the food particles between the teeth, so they don't cause the teeth to start decaying.

Do you floss? Every day? I didn't floss at all, until I had to have two fillings this spring. Now I do.

I started thinking, though, that Bible reading is a lot like flossing -- it's one of those tasks that everyone knows you should do on a regular basis, but we often say, "Oh, I don't have time for that today," or "Maybe tomorrow."

And reading your Bible is a lot like flossing in another way -- it's a way of cleaning out the garbage that your brain picks up on a daily basis, just from living in a messed up world. Every day, just from living in this world, you daily come in contact with bad attitudes, bad actions, and bad ideas (and this happens even when you're just hanging out with other Christians, because -- let's face it -- Christians aren't perfect either!). And these bad attitudes, actions, and ideas can get lodged in your brain, where they do not belong.

Reading God's word is a way of dislodging some of that stuff that can cause spiritual decay. Romans 12:2 says to renew your mind, and so in a sense, we could think of a regimen of regular scripture reading as your "mental floss."

A couple more thoughts about the idea of scripture reading as your spiritual floss or mental floss:

1. Just as you should never say, "Oh, I've already flossed 500 times, I don't need to do it again," you should never say, "Oh, I've already read God's word 500 times -- why should I bother reading it again?" The answer should be obvious; the fact that you've flossed in the past doesn't do any good when it comes to cleaning out the garbage you've accumulated now. In the same way, since you're continually collecting spiritual garbage in this world, the spiritual flossing needs to be ongoing as well -- no matter how many times you've already read it!

2. If I hadn't told you that I had two cavities, you never would have known it. In the same way, if you allow spiritual decay in your life, you can probably hide it from people for a long time. But if you hide it, and don't do anything about it -- if you pretend it doesn't exist -- sooner or later, everything will collapse in spiritual decay, and you (and everyone else) will be saying, "What in the world just happened?"
