Light

“You are the light of the world. A city situated on a hill cannot be hidden. 15 No one lights a lamp and puts it under a basket, but rather on a lampstand, and it gives light for all who are in the house. 16 In the same way, let your light shine before men, so that they may see your good works and give glory to your Father in heaven.

Matt 5:14-16 (HCSB)

You are the light.  Light shines.  It gives light to those who are in darkness.  Jesus reminds us that light was not meant to be hidden.  In fact when we try to hide the light it dims the light but it is still there.  Our lives are a testimony of what God can do with sinful humans.  When we hide our light we are taking away our opportunity to glorify God in our lives.  Don't hide the light but shine for all to see.
