After all, if you or I stood outside naked for several months in sub-zero temperatures, we’d soon be turned into frosty statues.
Trees can’t burrow into the ground and hibernate like bears, and they can’t fly south like migratory birds. They’re fixed in place, at the mercy of the elements.
And yet they somehow survive through the cold depths of winter. Why don’t they turn to ice, since, like other living things, they’re made mostly of water?
Their trick is something called “hardening.”
In autumn, trees in cold climates undergo a change whereby water flows out of their cells. The concentrated sugars, proteins, and acids left behind act as a potent antifreeze. The water now in the spaces between the cells is so pure that ice crystals can’t form. This ultra-pure water can be cooled to -40 degrees F and still remain an ice-free liquid.
Pretty cool, isn’t it?
But what is it that triggers the hardening?
Ah, this is where we can learn a lesson from the trees.
Has your head been spinning with all the changes the world has undergone in the past several years?
We stumble through one crisis, only to find another totally unexpected one emerge. We wonder if life will ever truly be the same again.
It’s at times like these that we need something that never changes, much like conifers.
During the winter, when deciduous trees are bare, I’m thankful for coniferous trees. These loyal friends, like the spruces, pines and firs, still have their mantle of green, which they’ll keep year-round. These silent sentinels might not be flashy, but we can count on them not to change.
God’s character is like that, too.
When the world seems to be in turmoil, and life is changing in ways that are distressing and unpredictable, we need something unchanging to hold on to. That something is our eternal Heavenly Father.
Some flowers have a trick up their sleeve (or up their petals):
They’re able to change colour.
I recently noticed a beautiful flowering plant heavy with pink blossoms in a neighbour’s garden. When I walked by several days later, I saw that some of the flowers had turned a lighter creamy colour as they matured. I did a double take and had to make sure I was indeed looking at the same plant as before.
Other flowering plants have the same ability to surprise us with shifting colours.
Among them is the aptly named “yesterday-today-and-tomorrow” plant. This tropical shrub has short-lived flowers which change colour as they age. They start out as purple, then shift to lavender and finally fade to white before dropping from the plant.
While flowers that change colour can delight and surprise us, sometimes we need something unchanging and constant in our lives.
Isn’t it good to know that we can count on God to always remain the same?
Many of us have GPS systems in our cars or on our phones. They allow us to pinpoint our locations on a map, letting us know exactly where we are.
But in the days before modern technology, how did people navigate? If they needed to cross an ocean, what told them where they were?
The North Star did.
More formally known as Polaris, the North Star is the brightest star in the Ursa Minor constellation. Because it’s almost in a direct line above the Earth’s north celestial pole, the North Star appears to stand motionless in the sky, with the other stars seeming to rotate around it.
This made it a perfect fixed point by which to draw measurements for celestial navigation. In fact, the Old English word for the North Star meant “ship-star,” reflecting its use in helping to chart a course when sailing.
We still need a north star today.
Not to get from point A to point B in our vehicles, but to navigate the seas of our lives. When our whole world has turned topsy-turvy, we need a fixed point to focus on to keep us on a stable course.
