Trees in cold climates prepare for winter through a process called “hardening.” Water drains from cells so they won’t freeze, expand, and burst the tree. The water that remains between the cells is too pure for ice crystals to attach. Its temperature may now drop to forty degrees below zero without cracking the tree. Trees harden at the same time each year because they take their cues from the fixed calendar of shortening days. They don't stake their lives on the weather, which may be unseasonably mild. They trust the sun, their one sure thing.

The Son who made the sun is surer yet. He is “the image of the invisible God, the firstborn over all creation. For in him all things were created,” and “in him all things hold together” (Colossians 1:15-17). Who tells trees when to harden each year? The same Son who makes the sun rise each morning and puts it to bed each night, pulls tides with the moon, whirls electrons in every cell, pumps your heart and inflates your lungs, and holds you when your heart is broken.

What holds the world together isn’t a force within nature but a person outside it. A person who entered the world He’d made so he could “reconcile to himself all things,” including you (v. 20). In this unpredictable world, you’ve got one sure thing. Jesus will “present you holy in his sight, without blemish and free from accusation” (v. 22).
