A friend was telling me recently about the new security systems on his car. Lane change detecter, detecter to tell him if he is approaching the car in front too quickly, integrated Bluetooth system, and he was telling me that some manufacturers are talking about incorporating a device that will detect if he drops off to sleep. All that to protect us, to ensure our safety, and to keep us in the right lane, at the right speed, and without going to sleep. These technological efforts are completely admirable, and perhaps they help us realize that our spiritual protection is just as important.
