It's good to carry a light with you as the night gets dark, especially in unfamiliar territory. Our phone spotlights come in handy when we come up to our cars on a dark parking lot, or as we search for the house keys when the porch light is off. Flashlights are a necessity wandering through dark woods on a mountain retreat or vacationing on the beaches at night.
The Jewish streets were rough, stony, and dark. Lamps were set up along walkways and torches were used as a guide in the wilderness. It was dangerous to go into unfamiliar territory without a light . . . animals, thieves, and rough terrain could cause serious harm . . . . even death!
It is no different for a believer today. As CHRIST-followers we need a guide. We need a GPS system to show us the way and light up dark paths. That is exactly what the Word of God is! It lights up dark and dangerous situations for us to see Truth and guides our very path from stumbling into deceptive lies which the world offers.
He will leave His light on for us! Do not turn it off!
