In a match between a ground squirrel and a deadly rattlesnake, whom would you bet on?
Remember, this is a ground squirrel: it can’t run up a tree to escape.
And if the squirrel needs to defend its burrow with its babies inside, it doesn’t have much choice: it has to stand its ground.
What chance does it have against a venomous rattlesnake?
More than you’d expect.
California ground squirrels have an ace up their sleeve.
When confronted by a rattlesnake, this squirrel is able to engorge its tail with extra blood. It then waves its tail back and forth vigorously, super-heating the blood.
The snake, while lethal, has relatively poor vision, so it can’t clearly see what it’s facing. It instead uses its built-in infrared sensor to detect heat.
The squirrel’s hot, blood-filled tail swishing to and fro mimics the heat signature of a much larger animal. The snake thinks twice about taking on such a formidable creature, and more often than not it slinks away, defeated.
The squirrel has been saved from its enemy by the blood.
And so are we.
On our own, we are no match for that serpent of old, Satan.
If your Mom is like mine, she’s probably given you some handy cleaning tips over the years.
She (or your Dad or caregiver) may have told you that you can use baking soda, vinegar or lemon juice as natural cleaning products.
She might have even told you about some surprising substances you can use to clean household items, like Coca-cola, mayonnaise, toothpaste or ketchup.
You may have been taught the secret to getting blood stains out of clothes: wash the fabric in cold water only. This is counterintuitive, because it’s the opposite of how you treat most other stains.
In the case of blood, however, heat will only set the stain and make it harder to remove.
It’s good to know how to deal with pesky stains: what substances to use to clean things, and what substances and methods not to use.
For instance, you’d certainly never use blood itself to clean anything.
Or would you?
Scripture tells us that there’s a special case where blood washes things whiter than snow:
When it’s the blood of Jesus.
If you had to guess, what would you say is the most valuable thing in the world by weight?
If you’re a cook, you might pick costly foods like beluga caviar or white truffles. Or perhaps the spice saffron, which can go for thousands of dollars per pound.
If you’re a jewellery lover, your mind might go to precious metals like silver, gold or platinum. You’d know that gold has been revered since ancient times, and sometimes goes for thousands of dollars per ounce.
You’d be getting warmer if you worked in industry and knew that some substances used in things like catalytic converters are very costly indeed. Rhodium and palladium are even more valuable than gold.
These would all be good guesses, but not even close.
What about diamonds as the most valuable thing on earth by weight? Very rare coloured diamonds such as the red can be valued at millions of dollars per gram.
If you’re a scientist, you might get closer by guessing plutonium, used to fuel nuclear reactors. Or you might figure you’ve hit the jackpot by picking antimatter, which might power spaceships one day.
This substance requires inconceivable amounts of energy to generate. It’s estimated that antimatter costs tens of billions or even trillions of dollars per gram.
But there’s one thing on earth more valuable than even that…
