conscience Swallowed by Design — a Glimpse of Wonder entry™ —
You may want to sit down for this one.
The average human produces about 1.5 quarts — or 1.4 liters — of mucus every single day. That’s enough to fill a large soda bottle. And here’s the kicker: you swallow most of it.
Yep. That drip from your nose? That tickle in your throat? It doesn’t just disappear. It’s working overtime — and then taking the express train down your esophagus.
But mucus isn’t just some gooey nuisance. It’s one of the body’s most underappreciated marvels.
Mucus acts like a biological flytrap. It’s sticky, stretchy, and surprisingly smart. It catches pollen, dust, viruses, bacteria, smoke particles — anything that doesn’t belong — and locks them in before they can reach your lungs or bloodstream. In fact, a 2020 study at MIT found that mucus can actually slow down or neutralize harmful pathogens, letting the body decide what gets absorbed and what gets tossed out.
And it’s not just in your nose.
Your eyes have a layer of mucus to keep them moist and clear. Your mouth and throat rely on it to coat tissues, trap germs, and move food smoothly. Your lungs use it to sweep out debris with little hair-like structures called cilia. Your entire digestive tract is lined with it — a slick, protective film that keeps stomach acid from eating you alive.
Even your sense of smell needs mucus. Scent molecules have to dissolve in it before your receptors can detect them. So technically, you smell through slime. Romantic, right?
Oh — and that thicker, stickier version that shows up when you’re sick? That’s phlegm — just mucus with more immune cells, ramped up to fight off infection. Think of it as mucus in battle armor. Gross… but glorious.
So where does it all go?
Mostly, you swallow it. All day. All night. Without thinking. And that’s the genius of it — this constant, quiet cleansing system that works behind the scenes, protecting you while you breathe, speak, taste, and move through the world.
And it made me wonder… what else in us works like that?
Our conscience comes to mind.
It’s not flashy. It’s not something we show off. In fact, like mucus, we usually only notice it when it becomes uncomfortable — when we feel that inner nudge or irritation telling us something’s not right. But that uneasy feeling is a gift. Like phlegm in the throat, it alerts us to spiritual irritants — pride, dishonesty, selfishness — and gives us a chance to deal with them before they spread.
When trained by God’s Word, the conscience becomes a filter — catching harmful patterns, softening harsh responses, even protecting relationships before they get infected. Hebrews 5:14 (NWT) says that mature people are “those who through use have their powers of discernment trained to distinguish both right and wrong.” That’s a mucus-level kind of maturity — silent, steady, and always at work.
So the next time you sniff, swallow, or clear your throat, don’t cringe. Be amazed.
Even your phlegm was designed with purpose. And your conscience? Even more so.
