Ever think of yourself as a light? We know the Bible says that Jesus is the "Light of the world." John 8:12. But He also says we are too, Matthew 5:14. Is your light shining and is it where it needs to be for others to see? If you're a light for this world then isn't it reasonable to think that Jesus wants you to shine where He placed you?
Think about this: a light doesn't make a noise to attract attention to itself. It is a silent beacon with a purpose to shed light on something else. Next door to our home is the Pitman Fire Department. They have a flag on their flag pole all the time, day and night. And proper protocol for flying an American flag at night is to have a light shining on it. And that's what is true of our fire departments flag. They've mounted a spot light on their building that shines a beacon of light on the flag. You don't necessarily see the light bulb, but you see the flag!
Jesus puts you in a place where your light can shine, but it doesn't so much shine on you as much as it shines through you and sheds light on your Savior and His love and kindness for this world. As a light, you're not seeking to draw attention to yourself, but as Matthew 5:16 reminds us, our light is to shine in order "that they may see your good works, and glorify your Father in heaven."
Don't hide your light. When you have an opportunity to do good for God's glory, then by all means, do good. You're where you are for a reason. And God certainly doesn't want you to hide your light. Let it shine!
