A friend of mine recently bought a Tesla electric car. Custom-made for each buyer, the car is elegant and  impressive on every level. As we sat at lunch, my friend took out his phone, opened an app and turned the car’s air conditioning on, so we could enter a cool car when we finished our lunch. After lunch, I was in a car that was twice cool.

Now, every time I fill my car with gas, to the tune of about $50, I will fantasize about driving a car that merely gets plugged in overnight and goes 300 miles on a single charge. Recharging an electric car does not, in any market, cost $50 every 5-7 days.

While it sounds like I am eager to justify the purchase of a Tesla, I am more interested in finding ways to conserve resources. I recycle plastics, glass and paper.I turn off lights in rooms as I leave them. I take showers that last no longer than three minutes. Taking seriously the responsibility to take care of the earth, I am trying not to be wasteful.

However, whether driving an electric or hybrid car, a Segway or riding a bike to work, most of us feel we’ve never done enough to conserve energy. Some have not, to be honest, given the idea much thought at all.

Papa God gave to Adam, the  command, “…fill the earth and subdue it.”(Genesis 1:28, NKJV). What does that mean today?  Are we to simply go along to get along? Are we to act as if we have left in charge? Are we to access natural resources and use them as if we have an unending supply?

Let’s take a walk and talk about it. Cost of the walk? Nothing.
