A typical lighthouse is a tall tower built near dangerous coastlines to help those navigating boats near the shore. Before the days of GPS, they served an essential role for those at sea. They stood as a warning to ships approaching the shore, as maritime pilots could see the light on the shore. In times of low visibility, they were able to create sound using horns, bells or cannons. Another purpose was to provide a navigational aid, as those on the sea were able to identify them by their varying stripe patterns. They also provided light for navigating into shore.
In the same way, Jesus is our lighthouse. His words warn us. His words guide us. Jesus warns us of dangers self-righteousness (Matthew 23) and the vanity of pursuing the world (Matthew 16:26). Jesus guides us in the ways of life, safe in the harbor. How appropriate that Jesus said, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life” (John 8:12).
