A hotel chain’s commercial featured one little building standing amidst a dark night. Nothing else was around. The only light in the scene came from a small lamp near the door on the porch of the building. The bulb cast enough illumination for a visitor to walk up the steps and enter the building. The commercial ended with the phrase, “We’ll leave the light on for you.” A porch light is akin to a welcome sign, reminding weary travelers that there’s a comfortable place still open where they can stop and rest. The light invites those passing by to come on in and escape from the dark, weary journey. Jesus says the lives of those who believe in Him should resemble that of a welcoming light. He told His followers, “You are the light of the world. A town built on a hill cannot be hidden” (Matthew 5:14). As believers, we’re to illuminate a dark world. As He directs and empowers us, “[oth- ers] may see [our] good deeds and glorify [our] Father in heaven” (v. 16). And as we leave our lights on, they will feel welcomed to come to us to learn more about the one true Light of the World—Jesus (John 8:12). In a weary and dark world, His light al- ways remains on.
