When 1 kilogram isn't 1 kilogram
Yet another reason to be thankful for the unchanging God of the universe. I found a story today about the standard cylinder with a mass of exactly 1 kilogram. It's kept in Paris and every year they measure other similar standards against it. It's THE standard used to measure everything from our medicine to buildings. Anything measured in grams or kilograms is measured against it. The problem is it seems to be losing mass. (Here's a link to the story from BBC news.) Not much, but nevertheless, it's losing mass - about a grain of sugar every so often simply disappears. The problem herein is clear - by definition, it can't change. Yet it does. Isn't it comforting to know that our God doesn't change. He is as timeless as the ocean tide and as secure as the sunset. He stands over time and above all changes. We don't have to worry about him changing because "Jesus is the same yesterday, today and forever" (Hebrews 13:5).
