Our Scripture reading today is Matthew 5:14-16.
 
Verse 16, "Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
 
We have a light to shine due to the fact that it is a light we were given from the Lord.  Our responsibility is to keep our lamps (life) clean so the light of Jesus will shine forth brightly to a lost world in need of hope.  This will bring more glory to our heavenly Father.  What a privilege it is to shine forth for Christ. 
 
“Christ never contemplated the production of secret Christians, — Christians whose virtues would never be displayed, — pilgrims who would travel to heaven by night, and never be seen by their fellow-pilgrims or anyone else.” (Spurgeon)
