You know those pictures of the world at night, when you can see all the city lights? Maybe that’s something like what God sees when He looks at the world — a great darkness with tiny spots of light wherever there is a Christian.
Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. (Matt. 5:14-16)
Do all things without murmurings and disputings: that ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world (Phil. 2:14-15)
How bright are our lights? Are we readily visible, contrasting sharply with the darkness, or do we blend in because we barely glow at all?
