The Cleanest Place in the World

What is the cleanest place on Earth?

If you guessed a room where semiconductors are made, you’d probably be right.

A microchip factory has to be exceptionally clean to avoid introducing contamination into the chip-making process. In fact, the air in their “cleanrooms” is filtered to be vastly cleaner than that of a sterile hospital operating room.

Anything that sheds particles must be avoided in a microchip cleanroom. Contaminants include human hair, dead skin cells, makeup, bacteria, and even micro-dust from pencils or paper.

So semiconductor workers must wear head-to-toe “bunny suits,” protective glasses, booties, hoods, face masks, and two pairs of gloves. These suits may include self-contained HEPA filter packs, because even human breath contains contaminants.

Let’s assume that I arrived one morning at a microchip factory as a new employee.

Let’s say I told the supervisor that I’d cleaned myself diligently in the shower that morning, washed my hair twice, gargled with Listerine, scrubbed my hands with bleach, and put on brand-new clothes. I was certain that I was clean enough to enter the factory.

The supervisor would say, “Hold your horses, Lori. You still have to put on a protective covering before you can come into the cleanroom.”

I might argue, “But I’m already cleaner than 95% of other people. I don’t need a covering. Let me in!”

My boss would say, “I’m sorry, but you’re not as clean as you think you are. We have very high standards here. You have to suit up first.”

Isn’t that sort of what entering Heaven is like?

The Polar Bear’s Secret

Pop quiz: What colour is a polar bear’s skin?

Did you guess “white”?

It’s the obvious answer, isn’t it, because their fur is white.

Surprisingly, though, you’d be wrong.

If you shaved a polar bear, you’d discover that it would look much like its cousin, the black bear.

That’s right: polar bears have black skin!

Don’t believe me? Here’s a clue: check out their noses and foot pads. They’re both black. Their thick fur so completely hides the blackness underneath that you’d never know it’s there.

Not only that, but polar bears’ fur isn’t actually white.

Pardon me?

It’s true! Their outer coat of fur consists of translucent hollow hairs that scatter and reflect visible light. These hairs have no white pigment, but merely appear white due to an optical trick involving the physics of light.

The polar bears certainly had us fooled, didn’t they?

And they’re not the only ones.

There are people whose lives have been so thoroughly changed by the gospel of Christ that you’d be shocked to discover their dark past.

The Best Cover-Up Of All

If you had guests coming over during the holidays, did you panic because your house was a bit of a mess? Did you try to make your place look neater by hurriedly scooping up a bunch of out-of-place objects from around the house and hurling them onto a bed, then hiding them under a comforter or blanket?

I’m not saying I’ve ever done anything like this, of course. I’ve just heard of other people who have.
