We live only a few miles from Camp Roberts, a National Guard training base on the Central Coast of California. As a result, I see contrails almost every day. Contrails are made from the exhaust of jet engines condensing behind the planes as they fly. This condensed water vapor forms trails that are actually long clouds. While they last, they decorate the sky with the evidence of the jets’ passing over an area. As the sun sets, they can take on the colors of sunset. And then, before you know it, they have disappeared.
This article has two sets of photos. The first set has four photos taken facing north or northwest. The second set was taken facing south or southeast. I left for a short walk to the mailbox as the sun was beginning to set. I noticed the contrails and took some photos. Then I got the mail. When I returned a few minutes later, I took a few more photos. Look for the contrast between the photos taken before I left and after I got back.
This was also taken when I got back, looking toward the north, across the cross street. You can see the contrails from that direction fading away. The earth has moved a bit, but it looks as though it's the contrails that have moved north. You can see they are fading and some are taking on sunset colors.
This should be contrasted with the photo above, taken toward the same direction. You can see the position of the moon. Notice how the contrails are now only whisps in the sky.
I began to think of the trail our lives leave behind after we are gone. How quickly our lives pass and are forgotten. They are ephemeral on this earth, which God brought into being by his Word. And the Bible says that only his Word lasts forever.
