I have a clock in my office. For months now the hands haven’t moved. It reads exactly the same time now as it did an hour ago, as it did last week, and as it did the week before. Here’s the thing. A clock’s very existence is to tell you the time. If it can’t do what it was designed to do then it’s little more than a decoration and has little practical purpose.

What do you think could be wrong with my office clock? If you guessed the battery, you’d be right! The battery was depleted and needed to be replaced or recharged.

Did you know that batteries were kind of discovered by accident? In the late 1700's a scientist named Luigi Galivani was dissecting a frog that was attached to a brass hook. He noticed that when he touched the frogs leg with his metal scalpel, the frog’s leg twitched. Although his original conclusion was wrong, Luigi had a colleague (an Italian physicist named Alessandro Volta) that came to the right conclusion.

Volta took Galivani’s work and expanded it. He experimented by joining two pieces of metal with a moist intermediate. Eventually he sandwiched dampened pieces of cloth between a number of metal plates stacked in a pile. Energy was given off and the first battery was invented.

Of course batteries don’t last forever. They work for a while and then they’re spent. Some brands last longer than other brands. Some raw materials are better for building a battery that lasts as well. For example, lead batteries don’t last as long as alkaline batteries. Lithium-ion batteries are rechargeable and are used in many applications (like your cell phones).

The way batteries work is similar to how you and I are designed. Every day we need time to recharge. The best recharge is to get a good night’s sleep. But sleep isn’t the only recharging we need. It’s a good idea to set a day aside to rest every week. The Word of God says that God made everything in six days and rested on the seventh (Ex. 20:9-11). God says that we should take a Sabbath or a rest day.

When I was growing up many stores remained closed on a Sunday (our chosen Sabbath) and we chose not to do any farm work. Even if we had crop out and it was a nice day to be harvesting the machinery remained parked. I’m not saying that we chose wisely. After all, Jesus said, “The Sabbath was made for man and not man for the Sabbath” (Mark 2:27).

Still, it’s important that we take time off of our work to rest. In an article titled “A Day of Rest: 12 Scientific Reasons It Works” Rhett Power asserts that most major religions call for a day of rest and that science agrees. In his findings, for example, he says that the benefits from taking a day of rest include a boost for your immune system and years are added to your life. All twelve of his scientific reasons are excellent reasons to take a Sabbath rest.

May I encourage those who find it difficult to take a day off to think about taking a day off. It’s how we were designed. I believe we honour your Creator when we do.

By the way, I went down to the drug store and picked up a clock battery. It works like a charm. Now, if you’ll excuse me, I’m going to head home to recharge.
