"You are light for the world. A city cannot be hidden when it is located on a hill." - Matthew 5:14 (GOD'S WORD® Translation (©1995))
Notice that Jesus isn't emphasizing that "He" is the light of the world (which He also is) but He is saying YOU are the light. His light should be beaming out of you. We aren't to try to hide our faith. It should be plainly seen by all those around us.
