Here is a great devotion reading by Kay Arthur:
“You are the light of the world,” Jesus declared to His followers in Matthew 5:14. And we know that light has one purpose: to dispel darkness. Light serves its purpose only when it shines forth, to be seen of men. If a lamp or candle doesn’t give light, what good is it?
Therefore Jesus admonishes us: “Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven” (Matthew 5:16).
I want you to notice something important here: our good works cause the light to shine. But those good works are to be done in such a way that they do not glorify us but our Father. If they do not point men beyond us to the Father, then something is wrong with the way we are letting our lights shine.
I’m not saying that it’s wrong for people to love and appreciate you. This is obviously going to happen if you’re used of God in a significant way in somebody’s life. That love and appreciation, however, should never stop with you. It should rather be primarily directed toward the Source of all Light, Jesus Christ. The lampstand is not significant, but the light that comes from the lampstand is. The lampstand is merely a vessel to bring light to those who are in its presence. Just as the moon reflects the sun’s light, so we are to reflect the Son’s light!
