Now the Lord says to me, “It isn’t enough for you to be merely my servant. You must do more than lead back survivors from the tribes of Israel. I have placed you here as a light for other nations; you must take my saving power to everyone on earth.”
Isaiah 49:6 CEV
You are the light of the world! A city on a hill cannot be hid neither does anyone place a light under a bucket rather it is placed on a stand for everyone to see. Let your light so shine before men that they may see your good works and glorify your Father in heaven.
(From Matthew 5, Jesus’s sermon on the mount)
