Several years ago I preached in the old Parish Church of Corstorphine, Edinburgh, on behalf of the Bible Society. The church building is very old in parts and has a little window in the eastern wall that has an interesting history. Before the city grew to its present size Corstorphine was a village, and on its east side there was a loch and a well-used pathway near the loch that wound its way through very marshy ground. To help people find their way the church always had a light in its little east window so that people would be guided by the light and find their way safely to the village.
Jesus tells those of us who are Christians that we are the light of the world. That means we have to be guides to people who are not Christians. Jesus also said "Let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven" (Matthew 5:17). Even when we may not be able to speak to people about the Christian faith the way we live will be a guide to them as to what is right and good.
Remember, Jesus himself is our great example. He is the Light of the world, so as we follow him our lives will also be lights guiding people towards the Lord himself.
Dear Lord Jesus, help me to be a guiding light to those who are still in the darkness of unbelief, for your name's sake. Amen
