When Jesus said, "Ye are the light of the world", what exactly did He mean? Too many Christians are trying to show the world their own light, when what Jesus really wants for us to do is to reflect His light in this dark world just as the moon reflects the light of the sun.
What does it mean to let your light shine? Jesus answers that question for us. He said that it is our good works that we do. It is clear from Scripture that good works do not save us, but if we know Christ as our Savior than our salvation will work its way out of us.
We are told to let our light shine before men, but exactly who are those that we are to be a light to? Those who are in darkness are to be the focus of our light. Just as Jesus came to seek and to save the lost, we are to go to those who are in darkness and show them the light of the Savior.
What is the purpose of letting our light shine? Jesus tells us that the end result of letting our light shine in this dark world is the glorification of God. That is to be the reason why we do everything that we do. When someone comes to know Christ as their Savior, that is one more life that God is getting glory in where He wasn't before.
