 This was challenging enough during the day, but at least there was light. But at night, road maps were doubly challenging since the interior lights in cars were rarely bright enough to make map reading easy. Light is a critical ingredient when navigating on the road or through life. When we encounter dead ends, roadblocks, detours, or other challenges when traveling through this life, we need the brightest light possible, Jesus Christ, the light of the world, and his word.
