God's changeless and everlasting. God doesn't deteriorate or have bad years. He's beyond space and time, the great I AM.
I was joking about absolute zero this morning with our low temps; "the temperature is near absolute zero, everything outside is 0K" as in zero degrees Kelvin.
I found an interesting passage on the definition of it in Wikipedia-
More formally, it is the temperature at which entropy reaches its minimum value, 0.
Everything changes and generally deteriorates, which is a crude run at the Second Law of Thermodynamics, we get more entropy and more change. We can't stop entropy by natural means, so the story goes.
What doesn't change? God. God is so cool, he reaches zero entropy. Ice Cube and the beer can can take a cease-fire in their coldness war and bow to the coldest one of all.
Yes, I am no PhD in hard science and you can nit-pick my metaphors until you've had your fun for the day. God does have a way of making some sense at those limit points like Absolute Zero or the Big Bang, where natural explanations start to get exceedingly funky.
