"You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house. Let your light shine before men in such way that they may see your good works, and glorify your Father who is in heaven."
- Matthew 5:14-16

The two main phrases in this passage are "you are the light of the world," and, "glorify your Father." The rest is explaining how we are special and that we should show our Christ-like lifestyle.
