LET YOUR LIGHT SHINE!
If He is the light of life in your experience, then that divine light must of necessity shine out through your personality and activity.
Paul reminds us: "Ye were sometimes darkness, but now are ye light in the Lord: walk as children of light" (Eph 5:8). If you have met Jesus Christ as Light of the World, then you will inevitably be a shinning light for Him.
If your reaction to that statement is that you are only an individual, and what good is your single small light in the dark world, then let me assure you that, just as the tiniest pin prick of light is visible in a dark cave, so, whether alone or with other Christians, the shining of your light is a reminder of the greater light which "lights the world."
